Hi @dwagner, thank you for your message and your feedback.
This workshop has proven to be very popular, and as such we have set aside a special infrastructure for participants. During peak times it may however still occur that the post-processor becomes temporarily unreachable for a number of users. This condition will usually recover after some time.
Please be aware that due to the same reasons, during high demand periods, loading of data may take longer than usual.
Regarding the crashes you mentioned, did that happen right-away after a session or some time after and what operation was being performed at the time?
