SISPI Observer Console froze for all observers (including the primary observer) 2 hours before the end of the night. We could not see the list of exposures in the Exposure Queue and in Exposure History. We had to rely on TA Claudio's screen to be assured that exposure was still in progress. Reestablishing the VPN connection after disconnecting it did not work, refreshing the browser did not work either. The problem did not seem to affect our access to observer2, only SISPI. After ~30 min, it came back to normal.
