Apologies for the downtime today
Nearly 12 hours of downtime is totally unacceptable and I apologise. The servers used to be hosted by Northstar Computer Services, run by Eric who's admin at BrickLink, but he recently sold the business to another company and this was the first time there's been a problem since then. Consequently I wasn't aware of the correct out-of-hours support arrangements and they were not totally familiar with the the server setup.
Anyway, we're back up now, and hopefully, if there is a next time, both they and I will be better prepared to deal with it.
