connection problems to

Since we returned from holiday the other day, I have noticed that some types of connections from some places are having trouble reaching (and all sites and services that also run on the same server). The problem is intermittent—certain things will fail for a while and then start working again, then fail some more. I don't yet know what causes this but I'm working on it.

Technical info: It seems that during some tcp setup sequences from some hosts at some times, most of the ack packets after syn packets are lost. The syn packets seem to get through in either direction. I have good (ie. root) control over some hosts on which this often happens, but if the problem is somewhere between the two then I may find it difficult to diagnose further.
