On two different FTP accounts, I am having problems uploading files. I can login and see the contents of the dir, and start an upload. Using Filezilla the transfer seems to always stall at either 0.9% or 1.2% (always those two numbers) and may simply hang, or keep restarting and then again stop at the same point. WindowsXP FTP is not great but I get similar types of problems there... it starts uploading and after a short while I get a timeout error.

FTP used to work fine, and I don't know if it's these accounts in particular (both have the same service provider although purchased on opposite sides of the world) or if "FTP is broken on my PC"... can that even happen?!
