@Shunketsu where are you in the world? There are some networks in Europe that are not renshuu, but most of renshuu's traffic from the main server to EU users run through those, and they've been severely congested this week.
I have heard of a couple of issues, but nothing widespread. It's a tricky thing - renshuu is NOT a big company, so I don't have the resources or expertise to make and maintain linked copies of renshuu on multiple servers around the world :(
