Yes, certainly something bad and I am not certain that it is fixed. My hash rate on the user stats graph froze at one number that looked like a plausible hash rate. On the user stats report, it was also frozen at a much lower rate and my round estimate tapered down to almost zero.
This despite the fact that both of my miners were reporting that they were running, connected and hashing. Of course, because the rigs thought that all was OK, they did not fall over to the other configured servers. I restarted my miners and my reported hash rates on the website look a lot better but the round estimate is still low though I would hope to see it rise.
I also note that the reported luck is way way down. It would be good to hear something from the siteops regarding what has been going on.
