As stated by a few other's PlusNET in the UK is definitely having issues. They do also have a thread open on their own forum, that is publicly accessible, and are looking into it. If a dev or rep could get involved with it, maybe it could speed things along. Link: http://community.plus.net/forum/inde...,118895.0.html

Although according to the thread it seems to be more a problem with their uplink suppliers than the routing within PlusNET themselves. There are a LOT of traceroutes within that thread that may help.
