What to Do When Your Website Goes Down (Troubleshooting Downtime)

Few things create more immediate panic for business owners than discovering their website is down. Every minute of downtime means lost revenue, damaged credibility, frustrated customers, abandoned shopping carts, and competitors gaining ground. For e-commerce sites, downtime directly translates to lost sales. For service providers, it means missed leads. For publishers, it means reduced advertising income.

However, website downtime doesn't have to devastate your business. The difference between minor inconvenience and major disaster comes down to preparation, rapid response, systematic troubleshooting, effective communication, and preventive measures. Many website owners make downtime worse by panicking, making hasty changes without diagnosis, contacting support without gathering basic information, or failing to communicate with stakeholders.

This comprehensive guide provides a complete website downtime troubleshooting framework for 2025: how to verify whether your site is truly down, systematic diagnosis procedures, common causes and solutions, emergency response protocols, communication strategies, prevention best practices, and long-term reliability planning. Whether you're experiencing downtime right now or want to prepare for inevitable future incidents, you'll learn exactly how to handle website outages professionally and efficiently.

Step 1: Verify the Downtime

Before troubleshooting, confirm your website is actually down—sometimes the problem is local, not global.

Check From Multiple Locations

Your location or network might be the issue:

Your Device: Try different devices (phone, tablet, laptop) Your Network: Test on cellular data vs. WiFi to rule out local network issues Different Networks: Ask colleague or friend to visit your site from different location VPN Test: Connect through VPN to test from different geographic region

If your site loads from other locations, the problem is your local connection, not your website.

Use Website Uptime Checkers

External monitoring tools verify global accessibility:

IsItDownRightNow.com: Simple checker testing from multiple locations Down for Everyone or Just Me: Quick verification service Uptime Robot Status: If you use monitoring, check your dashboard UptimeRobot.com: Offers free checking even without account

These tools test your website from various global servers, confirming whether downtime is widespread or localized.

Check Different Pages

Sometimes only certain pages or sections fail:

Homepage: Can you access main domain? Subpages: Do interior pages load? Specific Features: Does blog load but not checkout page? Admin Panel: Can you access WordPress admin or control panel?

Identifying which parts work versus which fail helps diagnose the root cause.

Browser Console Check

Technical users should check browser developer tools:

Open Console: Right-click → Inspect → Console tab Error Messages: Look for specific error codes (404, 500, 503, etc.) Network Tab: Check which resources fail to load Timing: See where connection fails (DNS, server connection, loading)

Error details guide troubleshooting direction.

Step 2: Identify the Error Type

Different error messages indicate different problems.

HTTP Status Codes

500 Internal Server Error What It Means: Server encountered unexpected condition preventing response Common Causes: PHP errors, corrupted .htaccess file, plugin conflicts, exceeded PHP memory limit Where to Look: Server error logs, recent code changes

503 Service Unavailable What It Means: Server temporarily unable to handle requests Common Causes: Traffic overload, server maintenance, resource limits exceeded Where to Look: Server load, traffic spikes, hosting provider status

502 Bad Gateway What It Means: Server acting as gateway received invalid response Common Causes: Server overload, timeout issues, firewall problems Where to Look: Server resources, PHP-FPM configuration, proxy settings

504 Gateway Timeout What It Means: Server acting as gateway didn't receive timely response Common Causes: Slow database queries, resource-intensive processes, server communication issues Where to Look: Database performance, script execution time, server logs

404 Not Found What It Means: Server can't find requested page Common Causes: Broken links, deleted pages, incorrect permalink settings Where to Look: URL accuracy, permalink configuration, redirects

403 Forbidden What It Means: Server refuses to fulfill request Common Causes: Incorrect file permissions, IP blocking, security plugin restrictions Where to Look: File permissions, .htaccess, security settings

DNS_PROBE_FINISHED_NXDOMAIN What It Means: Domain name doesn't resolve to IP address Common Causes: Domain expiration, nameserver misconfiguration, DNS propagation Where to Look: Domain registration status, DNS settings, nameservers

Connection Timed Out What It Means: Browser couldn't establish connection within time limit Common Causes: Server completely down, firewall blocking, DDoS attack Where to Look: Hosting provider status, server accessibility, traffic patterns

Step 3: Check Common Quick Fixes

Before deep troubleshooting, test simple solutions.

Clear Your Browser Cache

Cached versions sometimes cause false downtime appearances:

Chrome: Settings → Privacy and Security → Clear browsing data → Cached images and files Firefox: Options → Privacy & Security → Cookies and Site Data → Clear Data Safari: Preferences → Privacy → Manage Website Data → Remove All Quick Method: Try incognito/private browsing mode

Check Domain Renewal Status

Expired domains cause immediate downtime:

Verify Registration: Log into domain registrar account Check Expiration: Confirm domain hasn't expired Review Auto-Renewal: Ensure auto-renewal is enabled Payment Method: Verify credit card on file hasn't expired

Domain expiration is embarrassingly common and completely preventable. Set calendar reminders 60 days before expiration as backup.

Verify Nameservers

Incorrect nameserver settings break DNS resolution:

Check Current Nameservers: Use online DNS checker or registrar control panel Confirm Correct Nameservers: Match against hosting provider's documentation Recent Changes: If you recently changed hosting, verify nameservers updated correctly Propagation Time: DNS changes take 24-48 hours to propagate globally

Test Server Status

Hosting providers occasionally experience outages:

Hosting Status Page: Most hosts maintain public status pages (find via Google: "[host name] status") DreamHost Status: Check status.dreamhost.com for real-time infrastructure status Support Channels: Review hosting provider's Twitter or support forum for outage announcements Direct Contact: Contact support if status page shows no issues but site remains down

Step 4: Systematic Troubleshooting

If quick fixes don't resolve downtime, follow systematic diagnosis.

Check Server Resources

Resource exhaustion causes downtime:

Access Control Panel: Log into cPanel, Plesk, or hosting dashboard Review Resource Usage: Check CPU, RAM, disk space, and bandwidth usage Identify Limits: Compare current usage against plan limits Temporary Relief: If at limits, upgrade plan or optimize resource usage

Common Resource Issues:

• Disk space full (100% usage prevents write operations)
• RAM exhausted (causes crashes or slowdowns)
• CPU throttling (hosting suspends account for excessive usage)
• Bandwidth exceeded (monthly transfer limit reached)

Review Recent Changes

Most downtime follows recent changes:

Plugin/Theme Updates: Did you recently update WordPress plugins or themes? Code Deployment: Have you uploaded new code or made file changes? Configuration Changes: Modified .htaccess, wp-config.php, or server settings? DNS Changes: Updated nameservers or DNS records recently?

Rollback Strategy: If downtime started immediately after change, revert that change first.

Examine Error Logs

Server logs contain crucial diagnostic information:

Access Error Logs:

• cPanel: Metrics → Errors
• FTP/SFTP: Download from /logs or /error_log directory
• SSH: tail -f /var/log/apache2/error.log or hosting-specific path

What to Look For:

• PHP fatal errors pointing to specific files
• Database connection failures
• Memory exhausted messages
• Permission denied errors
• Timeout errors

Error logs often pinpoint exact problem file and line number.

Test Database Connectivity

Database problems cause widespread failures:

Check Database Server: Verify MySQL/MariaDB is running Test Connection: Use phpMyAdmin or database management tool Repair Tables: Run database repair if tables corrupted Check Credentials: Verify database username/password in configuration files

WordPress-Specific: If seeing "Error establishing database connection," check wp-config.php database credentials match hosting account settings.

Disable Plugins (WordPress)

Plugin conflicts frequently cause downtime:

Via FTP/SFTP:

1. Connect to site via FTP
2. Navigate to /wp-content/ folder
3. Rename plugins folder to plugins_backup
4. Test if site loads
5. If fixed, rename back to plugins and disable plugins one-by-one to identify culprit

Via Control Panel:

• Use File Manager to rename plugin folders
• Rename individual plugin folders to disable specific plugins

Check File Permissions

Incorrect permissions cause access errors:

Correct WordPress Permissions:

• Directories: 755 or 750
• Files: 644 or 640
• wp-config.php: 600 or 640

Fix Via FTP: Select files → File Permissions → Set appropriate values

Fix Via SSH:

find /path/to/wordpress/ -type d -exec chmod 755 {} \;
find /path/to/wordpress/ -type f -exec chmod 644 {} \;
chmod 600 /path/to/wordpress/wp-config.php

Examine .htaccess File

Corrupted .htaccess causes 500 errors:

Test by Renaming:

1. Connect via FTP
2. Find .htaccess in root directory (enable "show hidden files")
3. Rename to .htaccess_backup
4. Test if site loads
5. If fixed, regenerate .htaccess (WordPress: Settings → Permalinks → Save)

Check for DDoS or Traffic Spikes

Overwhelming traffic crashes servers:

Review Analytics: Check Google Analytics for unusual traffic spikes Server Access Logs: Look for repeated requests from same IPs Hosting Notifications: Check email for alerts about traffic or resource issues DDoS Indicators: Thousands of requests per minute from distributed IPs

Immediate Response: Contact hosting provider; they can implement server-level blocking or route traffic through DDoS protection.

Test SSL Certificate

SSL issues prevent HTTPS access:

Verify SSL Status: Visit site with https:// explicitly Check Certificate: Browser address bar shows certificate details Common SSL Issues: Expired certificate, mixed content, incorrect installation

SSL Testing Tools:

• SSL Labs Server Test: ssl-labs.com/ssltest/
• Why No Padlock: whynopadlock.com

Check CDN or Caching

Content delivery networks or caching plugins sometimes cause issues:

Cloudflare Issues: Check Cloudflare dashboard for errors Caching Plugin Problems: Disable caching plugin temporarily Purge Caches: Clear CDN cache, object cache, and page cache Bypass Test: Access site via IP address instead of domain to bypass CDN

Step 5: Emergency Response Actions

While troubleshooting continues, minimize business impact.

Communicate With Stakeholders

Transparency maintains trust:

Customers: Post on social media acknowledging issue and providing updates Team: Alert staff that site is down; prepare customer service for inquiries Partners: Notify business partners affected by downtime Status Page: Update status page if you maintain one

Example Social Media Post: "We're currently experiencing technical difficulties with our website. Our team is working to resolve the issue as quickly as possible. We'll post updates as we have them. Thank you for your patience."

Set Up Temporary Holding Page

If downtime will be extended:

Simple HTML Page: Upload basic "Under Maintenance" page via FTP Include Information: Expected resolution time, contact alternatives, social media links Professional Appearance: Maintain brand consistency even on error pages Monitoring Form: Optional email capture for update notifications

Redirect to Alternative

If you have backup options:

Social Media: Temporarily redirect to Facebook page or Instagram profile Subdomain: Use subdomain on different server for minimal functionality Third-Party Platform: Direct customers to marketplace store (Amazon, eBay, Etsy)

Document Everything

Record details for post-incident analysis:

Timeline: When downtime started, actions taken, when resolved Symptoms: Specific error messages and behaviors Solution: What ultimately fixed the problem Impact: Duration of downtime, estimated lost revenue/traffic

Documentation helps prevent future incidents and improves response procedures.

Step 6: Contact Support Effectively

When you need hosting provider assistance:

Gather Information First

Support resolves issues faster with complete information:

Error Messages: Screenshots of specific errors Error Logs: Copy relevant log entries Recent Changes: Document what changed before downtime Troubleshooting Done: List steps you've already attempted Urgency: Explain business impact (e-commerce, critical services, etc.)

Choose Right Support Channel

Live Chat: Best for immediate issues needing real-time guidance Phone Support: Complex issues requiring back-and-forth troubleshooting Email/Ticket: Detailed issues requiring research or escalation Emergency Hotline: Many hosts offer priority emergency lines for downtime

Reputable web hosting providers like DreamHost offer 24/7 support specifically for downtime emergencies, ensuring expert help is available whenever disaster strikes.

Be Specific and Clear

Poor Request: "My website is down, please fix it" Better Request: "My website shows 500 Internal Server Error as of 2:30 PM EST. I recently updated WordPress to 6.4.2. Error logs show: [specific error]. I've tried disabling plugins via FTP with no change. Please investigate server-side issues."

Specific information enables faster resolution.
