Failures in echo test:
Tech Circle has been at work trying to figure out what is going on, how these issues started to appear seemingly out of nowhere.
We had a meeting yesterday to try to balance the increasing number of reported issues, and the fact that holidays are here with most groups are running on skeleton crews (and we don’t want to risk breaking things more during this time).

Long Delays: I have seen no reason no rhyme to this. Some days echo test seems super fast, other times seems to take forever with the same setup. 
Fingers crossed this will be less of an issue on the new server.
