My first instinct was DNS caching or a local hosts file override, which is probably where most people go.
Start by clarifying that the issue is likely client-specific since others can access the site. Then systematically eliminate potential causes: local network, DNS, browser cache, VPN, or permissions. Finally, propose a structured debugging plan to confirm the root cause.
Pro tip: Mention that you would check if the site is accessible via a different network (e.g., mobile hotspot) to quickly rule out local network or VPN issues. This shows you prioritize efficient isolation of the problem.
Verify that the issue is isolated to your machine by asking teammates or checking from another device. This rules out server-side outages.
Test connectivity on a different network (e.g., mobile hotspot) and disable VPN to see if the issue persists. This identifies network-level blocks.
Flush DNS cache and check if the hostname resolves correctly. Also review the hosts file for any erroneous entries.
Try incognito mode or a different browser, and clear cache/cookies. This rules out client-side caching or extension interference.
Check if your account has the necessary permissions or if there are IP-based restrictions. Confirm with the team if any recent changes were made.
