i all:
We have a VPS with Media Temple. Their data center is somewhere on the westcoast. From time to time we have severe issues to connect from our Brooklyn/NY locations. We experienced the connectivity issue from 2 physical locations. Doing a tracert gave us a good result.
There are usually 4-8 users using our shop admin for order processing or the shopping cart for manual order entry. While they are having problems connecting from there, I can connect just fine from Calgary/AB, Canada. Most of the time no issues at all.
What could be the problem? Any hints on how to debug that?
My recommendation would be to contact mediatemple directly to solve this issue and ask them to do some diagnostics for you. This can be very likely an issue on their end.
