I know this is a strange problem, but here's what happens:
My connection is really spotty, and regularly goes down for a minute or so every 5-10 minutes. If I'm making a large transfer of many files to my website via FTP, and the site goes down, it can't connect again after the internet comes back up. Not only can my FTP client (Filezilla) not connect, but I can't reach the site in any way, via browser or otherwise. I know the site doesn't go down when this happens, because other people can reach it.
Any ideas? Thanks in advance!
