Anna University est en ligne
Les quatre méthodes de sonde (HTTP/1.1, HTTP/2, User-Agent de navigateur et curl HEAD) ont toutes atteint le serveur. Si vous n'y accédez pas, le problème est local, videz le cache DNS, changez de réseau ou désactivez le VPN.

Methodology
- Probe
- We send a GET request to the target URL with each probe method and time the full response.
- Counts as DOWN
- Every probe method fails the request (connect refused, DNS error, timeout, or HTTP 5xx).
- Counts as DEGRADED
- At least one probe method succeeds but at least one fails, the site is up but blocking or mishandling a specific request type.
- Detail
- Per-method results include HTTP status code, response time, and best-effort DNS / connect / TLS / first-byte phase timings when the Node HTTP client exposes them.
- Cadence
- Every 5 minutes, in parallel across 4 independent probe methods (HTTP/1.1 with strict TLS, HTTP/2, a browser User-Agent GET, and a curl-style HEAD) from our edge network. We check probe diversity, not geography — if a site blocks a non-browser User-Agent or only speaks HTTP/1.1, the four cards show it.
- Rate-limited targets
- If a host returns 429 or consistently drops connections from our IPs, we cap retries at 3 and report the last observed status, we do not flood the target to confirm the outage.
- Data source
- Our verdict is based on direct multi-method probes, every result above is a live network request, never a Twitter mention or DownDetector aggregate. User reports, when shown, appear separately below as a supplementary signal and are never used to determine the up/down verdict.
Common questions
Why is Anna University down right now?
Anna University outages are usually caused by server overloads, failed deployments, CDN or DNS problems, DDoS attacks, or regional internet routing issues. isitdown.io checks Anna University via 4 probe methods (HTTP/1.1, HTTP/2, a browser User-Agent GET, and a curl-style HEAD) simultaneously. If all 4 fail, Anna University is down for everyone. If only some fail, Anna University is up but blocking or mishandling a specific request type. If all pass but you still can't connect, the issue is on your local network, VPN, or DNS.
How can I check if Anna University is down for everyone or just me?
Click "Check Anna University now" above. isitdown.io pings annauniv.edu via 4 probe methods in parallel and reports which ones succeeded. If all four pass, the issue is local, try flushing your DNS cache, switching networks, disabling your VPN, or using a different browser. If two or more methods fail, the outage is on Anna University's side.
