Is IIT Delhi Down?

IIT Delhi – Service-Specific Troubleshooting Guide

If you're experiencing issues with IIT Delhi (https://home.iitd.ac.in), try these troubleshooting steps:

Basic Steps

• 1. Refresh and Retry: Press Ctrl + F5 (Windows) or Cmd + Shift + R (Mac) to perform a hard refresh. This clears the cached version of the portal and often resolves loading or login glitches.
• 2. Check Your Network Connection: Ensure you are connected to a stable internet connection. If you are on-campus, try switching between the IITD WiFi and a mobile hotspot to rule out a local network firewall issue.
• 3. Switch Browser or Use Incognito Mode: Try accessing the portal in a different browser (Chrome, Firefox, Edge) or open a private/incognito window. Disable browser extensions like ad-blockers or VPNs temporarily, as they can interfere with the login redirect.
• 4. Clear Browser Cache and Cookies: Go to your browser settings and clear all cached files and cookies for home.iitd.ac.in. This is especially helpful if you see a blank page or "ERR_CONNECTION_RESET".
• 5. Verify the URL and Date/Time: Make sure the address is correctly typed as https://home.iitd.ac.in (not .com or .org). Also, check that your device's system date and time are correct – incorrect time settings can break SSL/TLS handshakes.

Intermediate Steps

• 1. Test the Service via Mobile Data vs. Campus Network: If the portal works on mobile data but not on the campus LAN/WiFi, the issue is likely a local routing or DNS problem. Try flushing your DNS (ipconfig /flushdns on Windows, or sudo dscacheutil -flushcache on macOS).
• 2. Check for Scheduled Maintenance (Internal Portal): The IIT Delhi home portal often undergoes maintenance between 2:00 AM – 4:00 AM IST. If you are facing issues during this window, wait for it to end. Also, if you see a specific error message like "Service Unavailable – IISR," note that it may indicate a backend server failure specific to the academic records module.
• 3. Inspect Proxy and SSL Settings: If you are using a proxy or a custom SSL certificate (common with Kite / Kerberos authentication on campus), ensure your system trusts the institute's root certificate. Disable any "HTTPS scanning" in antivirus software temporarily to test.
• 4. Try the Alternate Domain (Legacy Portal): IIT Delhi has an older mirror at web.iitd.ac.in for the homepage. While we do not recommend bypassing the primary URL, testing the alternate domain can help you identify if the issue is isolated to the main server's load balancer.

Still stuck?

If after these steps the IIT Delhi portal is still not loading for you, it is likely a broader outage. Please click the 'Report Outage' button on this Is It Down Bro? status page to let other users and our monitoring system know. This helps confirm whether the issue is widespread or isolated to your network.
