Im also on an 100mbit line, maybe try an ping or tracert to eu.middlecoin.com
Ping is good and tracert showed 15 hops which most of them is inside of Sweden before leaving for the cloud and ending up at amazon after 32ms.
eu is rock solid for me today. Friend has reported issues with it tho, he hasnt had issues before
EU has been rock solid for me when others have complained about it, so it must be some kinds of routing issues from the data-center.
