It was fascinating to watch the higher block chain continue to build. Was it ignorance by some large miners? Or was it an intentional attempt to keep the blockchain forked.
No, it was night. I woke up at 3am thanks to one guy who called me over skype. I have a lot of monitoring scripts which trigger SMS alert when something bad happen on pool, but there was almost no chance to catch this, because the bug wasn't in bitcoind 0.8 used by the pool, but in previous (and still widely spread) bitcoind 0.7.
