Our broadband went on holiday today leaving us stranded on an internet desert island. You don't realise quite how much you use the WWW until it's not there.  If you sent us an email today and haven't yet had a reply from us it might have been used to pay for the gremlins holiday, so could you send it again?  We'll deal with any missing missives in the morning.
Thanks for your patience.
(for once it wasn't our system, it was BT, and it wasn't just us!)
