Southperry Minecraft Server V2

I've been noticing a large amount of lag recently on the FTB server. My connection is fine (including connected to the server, it's green), and other people have mentioned having lag at the same time as me. I think it has to do with the FTB server specifically, because there's no issues in the Survival server, but it's laggy on the FTB server.

The kind of lag I've been running into is: delayed pickup, blocks have to be broken multiple times to actually disappear, and sometimes they just reappear then disappear again several seconds later. Makes it hard to really do much.

I've been having sporadic internet issues for the past 2 days. If it continues, I will contact my ISP (Though I don't know if this is the problem, it may be from everyone's machines).
