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.
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.
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.
