Not only one but both. The connection is slow but normally both servers can get in pace with the upstream. However, in late October, we has performed an storage upgrade on the server in question, which made the sever missed several updates during that time in a few days. After it brought back online, it was not put into service immediately but a manual sync from the other server was performed. After the successful sync, the server in question was put back online. Because the re-sync itself took a long time, a few updates for debian was missed, which made a large amount of data to transfer in the later sync from syncpxy.cna.d.o. With as slow connection speed as about 1 Mbps, such transfer could not be completed in an appropriate time. I first didn't realize it and tried to restart the ftpsync for many times but such measure made no luck. Finally, I manually started rsync from its peer and then started the normal ftpsync. Everything worked fine after that. What I want to emphasis is that such slow connection to syncpxy.cna.d.o won't lead to problems if the servers are kept in pace with the upstream. But it can be a problem if a server is out of sync for one or two days. I think maybe another account on syncproxy2.wna.d.o can be opened and we can get a faster connection. > > Sorry, but this have been a problem for too long.
