Apologies guys - you were all meant to be asleep
scheduled maintenance from c. midnight to 4am by my technical guys, with some quite detailed restructuring of where things are in the datacenter...
for some reason a number of servers didn't go back up again (they probably forgot to plug them in!)
Thanks to a member on here who texted me to let me know (our usual monitoring system tells me if a server goes down, but can't tell me if it fails to go up after a planned outage...)
amazingly not a single one of my paying clients seemed to notice that their websites weren't back up
Talking of which I like the idea of doubling my fees - form an orderly queue over here...
for interest our servers are in a very robust and fail safe datacenter in Manchester - but this was probably human error!
