Is ISRO Down?

ISRO Service Troubleshooting Guide

If you're experiencing issues with ISRO (the Indian Space Research Organisation website and its associated portals), try these troubleshooting steps:

Basic Steps

• 1. Verify your internet connection: Ensure you have stable connectivity. Try loading other government or high-traffic websites to confirm your network is functioning. If using a mobile connection, toggle airplane mode on and off.
• 2. Check if ISRO is under planned maintenance: Space agencies often schedule downtime for data uploads, mission telemetry updates, or portal enhancements. Visit the homepage and look for a scroll ticker or banner indicating scheduled maintenance windows.
• 3. Clear your browser cache and cookies: Outdated cached data can cause page elements to fail to load. Go to your browser settings and clear recent history, then refresh the ISRO site.
• 4. Test with a different browser or device: ISRO's site is information-heavy with multimedia content (mission galleries, live telemetry). If it fails on Chrome, try Firefox or Edge; or switch from desktop to a mobile device to rule out local browser extension conflicts.
• 5. Disable VPN or proxy services: Some ISRO-backed resources restrict access from non-Indian IP ranges or anonymized connections. Temporarily disable your VPN and try accessing https://www.isro.gov.in directly.

Intermediate Steps

• 1. Flush your DNS cache: ISRO's domain resolution can sometimes be stale. Open your command prompt (Windows) or terminal (Mac/Linux) and run: ipconfig /flushdns (Windows) or sudo dscacheutil -flushcache (Mac). Then reload the page.
• 2. Check for specific portal/service failures: ISRO hosts multiple subsystems, including the Shukrayaan mission updates, PSLV/Cy3 launch broadcast pages, and the resource download center. If the main site loads but a specific mission page doesn't, the issue may be tied to that sub-service's backend, not your connection.
• 3. Test with a different network (hotspot or ethernet): Some institutional or office networks block large payload downloads or streaming video (used during live launches). Try switching to a mobile hotspot to isolate if your current ISP or firewall is throttling ISRO's content distribution.
• 4. Review browser developer console for mixed content errors: Press F12, go to the console tab, and reload the site. If you see errors related to SSL certificates or mixed content (HTTP vs HTTPS), your system clock may be off, or your browser may lack the required root certificate updates for secure India.gov.in subdomains.

Still no luck? If after completing these steps ISRO remains inaccessible for you, please click the Report Outage button on this Is It Down Bro? status page. That helps our independent monitors track widespread regional or ISP-level outages affecting the service.
