Dan, there isn't one when that happens, it just says failed. Obviously this is the way it often goes in general:
Success
Success
Success
Failed, 404
Success
Success
But it's like it just suddenly decides to do it and it just starts going down the list at a really fast pace failed, failed, failed, failed etc. It's as if it just gives up.
So far today I have about 800 successes and 170 general fails (timeouts, 404 etc.) and it hasn't done the mass 'Failed' yet. But I know it will eventually.
Steve.
