I don't see anything about these tests that would say much. It could be environmental but it might just imply that all the timeouts should be higher if they are sensitive, or their was (and continues to be) an outage of some sort.

Assignee chosen because I see you as reviewer of avro changes and author of other changes to the py sdk in the last few days. If you have no idea, that's fine, I just didn't want to leave it unassigned.
