It seems to be sporadic (I'm talking about the mining servers) as once in a while it would accept shares, then it would follow by a series of 10 to 20 connections errors, and then accept 3 shares or some random number.
Maybe another DDoS?
Well, I can't access the site at all, and it said right before I refreshed the page (while I could still access it) that there had been changes to the server.
Methinks someone doth play with IPtables too much... but yeah, it could be DDoS too
EDIT: My miner has switched back and the website is up again.
