No worries though! Your systems administrators should be able to sort it out. There's a couple of ways they can look into this. Ask them to:
1) Run a ping/traceroute test and an MTR test. Those should be performed for both www.e-goi.com and www.e-goi.co.uk. If you can login into your account, make sure to run them for bo[serverID].e-goi.com as well (check your browser's URL bar after logging in to find out which [serverID] was assigned to your account).
2) Download iPerf (a small network diagnosis tool) and run it for iperf.e-goi.com .
These tests should be enough for your tech folks to figure whether something is amiss in your connection and how to fix it.
