Something brought down my shared server today, and it had to be rebooted. Apologies for the downtime. What happened is completely opaque to both me and the tech support; the only mildly suspicious item in my recent logs is 627 recent access requests from 18.104.22.168, a Brazilian ISP. I don’t have that many readers in Brazil, as far as I know.
But that alone really shouldn’t have been enough to bring everything to a screeching halt.
Of course, it could have been something done by one of the people with whom I share the machine.
