The problem was reported and has hopefully been resolved. But I'll be keeping an eye on it. |
Thanks for the update. The connection seems ok here now  . |

| The problem was caused by someone running 7za on the server. For some reason, even just a single instance of that program created a load 30 times greater than the server could keep up with. Maybe it was due to some kind of bad pattern of disk I/O or heavy multithreading. In any case, steps will be taken to ensure it doesn't happen again. |

| Oh, I see it now. At some point there were two 7za processes running. The two together allocated a very large amount RAM, which caused swapping, which slowed the server to a crawl for a while. |
