I apologize for HalSail going down at about 14:30 yesterday, 2nd March. It came back up today at about 09:30.
The problem was at the hosting company. They attempted to change some hardware and made a mess of it. They got it back up eventually, but had to revert to a backup made at 03:30 on 2nd March, so any data that was put in between then and 14:30 was lost.
The hosting company assures me that it will not happen again and I am keeping a very close watch on them.
