Due to a peering slugfest between Cogent Communications and TeliaSonera, TeliaSonera customers have been cut off from Cogent's network since March 14th. The Stardock network (which includes ICO servers) is under Cogent, so multiplayer Sins has been impossible for these past two weeks for TeliaSonera customers (proxy servers are too slow and unreliable.) Of course, this also affects all other Stardock games and applications.
TeliaSonera is one of the largest networks in Europe; this peering dispute literally affects millions of people. Both sides of the dispute claim that the other side is at fault, but currently it appears that Cogent is the one that "flipped the switch" to partition the Internet.
Disrupting Internet traffic for millions of people as a negotiating tactic is something that probably shouldn't be rewarded. Could Ironclad / Stardock please indicate their displeasure to Cogent for cutting off their access to millions of current and potential customers? If you haven't already done so, of course.
