It happens again at this moment!
there are no unusual drops in connections/second or P2P lookups/second in the Stratus logs at or near the time you posted, nor any other suspicious activity patterns at other times that i've noticed. Stratus appears to be functioning normally.
Any idea where to look for the root cause?
Any place where to find Stratus availability?
the most likely cause is a network problem somewhere between you and the Stratus servers, which are located in California, USA. the Stratus servers don't respond to ping, but you can traceroute toward them and get most of the way there. compare a traceroute during an "it's working" period with one from an "it's not working" period to see if/where a network breakdown is potentially occurring. unfortunately, given the asymmetric structure of the Internet, this technique might not show you exactly where the error is, but it might at least demonstrate that there's *an* error somewhere along the forward or return path.
there is no Stratus status page.
