Please check back here for updates.

Update 5/7/08 11am Pacific — We have narrowed down the problem to only affecting customers using the following ISPs: AT&T/Sbcglobal, Comcast and RoadRunner. We have tested the following solution with the help of one of the affected customers, so this should work for all: You will need to change your ftp-only user to sftp to go around what we suspect to be bandwidth throttling affecting only FTP connections.

Edit your ftp-only user to be sftp in the control panel under Users/Manage Users ( https://panel.dreamhost.com/index.cgi?tree=users.users& ). This should schedule a user update, and as soon as the little clock next to your username in the control panel is gone, log in with that user using the SFTP settings on your upload client, and you should be able to upload the large files. If your current client doesn’t have SFTP connection, you will need to download another one.
Please note, if you’re already using a shell user to connect through ftp, then all you need to do is change to sftp in your client, you don’t need to modify your user.

If the above doesn’t make your problems go away, then it’s most likely unrelated. Please send support a message, so we can look into it for you.

Update 5/8/08 9am Pacific — Apparently Verizon and other ISPs have been added to the list. Even if your ISP is not listed, please try to change to sftp, and if that doesn’t work, let us know with as many details as possible.

Update 5/8/08 10:50am Pacific — We’re continuing to look into this problem to make sure it’s not something on our end that’s causing the connection drops. We have just tested a few more cases were the customer switching to SFTP didn’t make a difference, but so far we couldn’t replicate the problem, but we’re still checking, examining more data.
In the meantime, continue trying to switch to SFTP to try that way. We recommend that over FTP anyway for its security. If you’re using telnet, you should be switching to ssh instead.

Here’s a link to the article in our Wiki regarding the use of SFTP…

Update 5/09/08 8:15pm Pacific — We’re still looking into this issue, and thought it was resolved for most users, however, that doesn’t seem to be the case. At this point, all tests we’ve run on users mentioning problems come back working 100%. We’re unable to verify the problem at all, other than the support that’s coming in about it. We do have some support personal on some of the effected networks, and will be doing tests.

We apologize for the delay in getting this fixed, however, it’s not reproducible on our end, at all, so that makes it even that much more difficult to track down. We’ll keep updating, the more info we have.

Update 5/10/08 7:45pm Pacific — Ok, this still seems to be happening, however, we may have found a way around things. We’ve tested on a known problem network, and the test went through correctly. Please try FTP again, as some head way in the issue has been made. If not, hold tight, we’re still working on the problem!
