Start here

A cleaner triage path for common website failures

The fastest way to recover a broken site is usually to narrow the blast radius before making deeper application changes.

Step 1

Confirm the visible symptom

Start with the exact browser error, dashboard failure, or outage pattern so you can narrow the first safe fix.

Step 2

Work from DNS and HTTPS inward

Check DNS resolution, certificate coverage, proxy status, and origin reachability before touching application code.

Step 3

Validate after every change

Retest the affected route, login flow, or admin action after each update so you know what actually restored service.
