Problems: 

When the last observer joined for the ToO at the end of the night, the SISPI keeper was found unresponsive. We called people in the control room and it was very slow also for them. They had to close some of the chrome and safari windows and things started working again. In order to have a responsive keeper for SISPI we had to limit the windows to 2 chrome and 1 safari. This is not ideal.

In addition, the remote observer was not able to load SISPI with the keeper link - it would get stuck to 'loading'. The other remote observer at the time was able to see and control SISPI through the keeper link. However, the remote observer who had issues opening SISPI keeper, was able to open and use the keeper with the kentools. In the end we had to give control though zoom to SISPI at the ToO observer.

There was no time loss because while people in the control rooom were troubleshoothing, I managed to upload the scripts using my personal keeper (KBoutsia).
