BOTpool is now the same the same as TAG, IT and HASH... and the Explorer on 27573 as well...
All pools and explorer are on 27574 at the moment with matching matching difficulty of 70.
Have look at the orphans on all the pools... BOT got hammered... even Scryptmining had an orphan... the only reason IT has no orphans is because there is only 5Mh/s there at the moment.
Fuse... here is the orphan problem exposed.
EDIT - Both times I have seen this... it started with BOT getting hit with literally double hash-rate... 2500Mh/s and 1900Mh/s... the only reason I picked it up either time is because I have miners spread across several pools and notice that 'current block' and 'difficulty' does not match... and each time BOT was holding massive hash-rate, then lagged out and then taken off-line and restarted. Last time BOT was offline for quite a while and TAG was the fail over as the hash-rate doubled quickly... but each time the difficulty drops dramatically and there are lots of orphans.
