Often the problem is not that they cannot find a reason why, but before that, they cannot even see it, i.e. they can't put the hands around it.�� Its human nature that we deal with the world through our own experiences.�� If a problem can't be seen, how can it be solved.

Without know what actions they may have tries, I'd generally say it seems that it can't be solved with local testing since that is a different environment.�� Ideally your DevOps guys could get on a machine in a remote corner of the world exhibiting the problem, to help them "see" the problem.�� That said, right now��for me from different location its not too bad. Perhaps it only get in a twist with lagged/dropped packets on poor networks.�� Do they test using tools to simulate poor networks?
