No user reports for C-DAC in the last 24 hours — usually a sign that everything is running normally.

Our automated checks run from our own monitoring server and test the public website — they can miss problems that only appear inside the mobile app or after you sign in. The status on this page also reflects recent user reports, so read it as a community signal rather than an official announcement from the company.

About C-DAC

C-DAC is a government portal tracked here (www.cdac.in). These portals sometimes slow down during scheduled maintenance or heavy deadline-day traffic — keep any application reference numbers handy.

Fix it yourself

Five quick things to try before concluding C-DAC is down.

  1. Hard-refresh the page — press Ctrl+Shift+R (Cmd+Shift+R on Mac) so C-DAC loads a fresh copy instead of a stale cached one.
  2. Switch your connection — move between Wi-Fi and mobile data to rule out a local network problem.
  3. Try incognito mode — a broken browser extension or corrupted cookies can stop C-DAC from loading while it works fine for everyone else.
  4. Swap the app and the website — if the app fails, try the website (or the other way round) to see whether the problem is limited to one platform.
  5. Wait it out — if our live check also fails, the fault sits on C-DAC’s servers and usually resolves on its own; check back in 15–30 minutes.

Frequently asked questions

Is C-DAC down today?
Check the live status above — government portals slow down or crash most often near last dates for applications and results. If reports are spiking, thousands of others are facing the same thing, so it is not just you.
Why is C-DAC portal login not working?
Delayed OTPs and heavy traffic are the usual culprits, especially close to deadlines. Also confirm that your Aadhaar-linked mobile number is active and receiving SMS. Trying early in the morning, when traffic is lowest, fixes this for most people.
I am not getting OTP on C-DAC. What can I do?
Check your signal, turn off DND for transactional SMS, and make sure your inbox is not full. Wait for the full cooldown before hitting resend — requesting OTPs too fast can temporarily lock you out.
The C-DAC website is very slow or keeps timing out. Why?
Government sites are built for normal traffic and buckle under deadline rushes. Avoid peak evening hours, keep your documents ready so you finish in one session, and retry during off-peak hours if a page times out.
My application on C-DAC failed midway. Is my data lost?
Often not — most portals auto-save drafts as you go. Log back in and look for a drafts or incomplete-applications section before starting over. Always save acknowledgement numbers and screenshots of every successful step.
