Is it Microsoft Teams, or is it you? Test your own connection against Microsoft Teams — one verdict in 10 seconds.Microsoft Teams is responding, but slowly — 20 ms to first byte (normal is under 1500 ms). That reading is from itsnotyou's monitoring servers, 47 seconds ago.
It can be either — that's the hard part. The status on this page is measured from itsnotyou's monitoring servers, so Microsoft Teams 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.
A slow Microsoft Teams usually comes down to one of two things: Microsoft Teams'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.
Microsoft Teams 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.
Chat goes over ordinary HTTPS while meeting audio and video need UDP media ports. Corporate firewalls and VPNs commonly block those ports, so chat succeeds and calls fail. That pattern almost always means your network, not a Teams outage.
