Common reasons Stack Overflow looks down when it isn't

What to check before blaming Stack Overflow

  1. Open a question page while logged out — if it renders, the site is up and the problem is your session.
  2. Disable extensions or try an incognito window if the editor or vote buttons do nothing.
  3. Check whether the action you are blocked from needs more reputation.
  4. Try another Stack Exchange site to see whether the whole network is affected.

Stack Overflow status — frequently asked

Is Stack Overflow down right now?

Stack Overflow is up and responding in 20 ms. That reading is from itsnotyou's monitoring servers, 2 minutes ago.

Is it Stack Overflow that's down, or is it my internet connection?

It can be either — that's the hard part. The status on this page is measured from itsnotyou's monitoring servers, so Stack Overflow can look healthy here while your own connection is the real problem. The itsnotyou test checks both at once and returns a single verdict in about 10 seconds.

Why is Stack Overflow loading slowly?

A slow Stack Overflow usually comes down to one of two things: Stack Overflow's own servers are responding slowly — itsnotyou measures time to first byte, and anything over 1500 ms is flagged as slow — or your local connection is the bottleneck. Running the test tells the two apart.

How often is Stack Overflow's status checked?

Stack Overflow is probed every few minutes, around the clock, from itsnotyou's monitoring servers. The verdict and the 24-hour response-time history on this page update automatically.
