There's a thorn with every rose, and in the line of broadband Internet, ain't that a fact? We've heard about Time Warner Cable and World of Warcraft connectivity issues before, but this new ISP issue is packing smoke. Subscribers of Tiscali are disgruntled at the apparent blocking of peer-to-peer (P2P) connections by their ISP. Even multiplayer connectivity is also hampered, as complaints roll in from players on EVE Online, CoD4, and ET: Quake Wars.

Telecommunications company Tiscali provides internet services in Italy, Czech Republic, The Netherlands, and more importantly, UK. Now, some PlayStation 3 (PS3) users report that they get disconnected from the PlayStation Network (PSN) during peak periods.

The consumers informed the ISP about it and Tiscali admitted that there's indeed a problem. According to the company, the connection usually works without any issue whatsoever. But during peak times, they try to allocate the limited bandwidth equally among users through a technique known as traffic shaping.

"We are however unable to commit any timescale as when the migration will complete. Please note that this is not a major issue and is only affecting a handful of customers," said Tiscali in a statement. The company added as well that the problem is not isolated with PS3 users as its MSN service has also been affected.

They made sure, however, that their engineers are currently trying to work out a solution. Well, some ISP uses the same technique and there are no reports about users being disconnected yet. We do hope that they find a fix soon especially now that the PSN figures are looking good.
