The "disk full" error has nothing to do with your account(s); it means that the physical storage that you are all sharing is nearly full. (Remember that there are thousands of accounts on each server, all sharing the same SAN partition.) That means that the admins will have to clean up a lot of temp and log files, and will probably can high-usage accounts for files that shouldn't be stored according to the terms of service. If that doesn't clear up enough space, they may have to provision more storage. In the meantime, uploads will be prevented so that files don't get truncated/corrupted. It will take some time, but things will be back to normal before too long.
