No idea if this helps. Just trying to. There's file transfer issues.

https://apps.foldingathome.org/serverstats
(140.163.4.231 + 140.163.4.241)

Assign rate of 3600/hr is exactly 1/second.

Seems too much of a coincidence. Throttling? Thread.Sleep(1000) ?

140.163.4.231; hover over Yes for "Has CS" - "Failed: 140.163.4.241"
140.163.4.241; hover over Yes for "Has CS" - "Failed: 140.163.4.231"

These 2 servers use each other as a collection server? Not a comment, just a question.

I'm failing to upload to 231 with PLEASE_WAIT. Closed client to prevent 9th+ retry/overload (12.58MiB each try).

Thanks all.

No, it's not a coincidence. The servers run out of bandwidth before they reach other limitations, so they are intentionally bandwidth restricted.

It's reasonable for the two servers at mskcc.org are on the same campus and are managed by the same person, it's reasonable to use them as CS for each other. They can relocate WUs collected by either CS to the WS over a very fast local link.

Unfortunately that does leave some equipment that could cause common mode failures (like the campus electrical utility/grid or even the campus routers).

Persoanlly, I wish that a third CS could also be added, but I don't think FAH is equipped to do that yet.

Hovering over Has CS also shows Accepted:fah4.eastus.cloudapp.azure.com its just that they are setup correctly to use each other as CS.
