This is a bit of a weird one, folks.
When you try to access any of the services hosted on quantz over the T-Mobile US cell network (specifically tested with p.qa.d.o and qa.d.o), you end up getting a 504 Gateway Timeout after an approximately 30 second wait.
paultag and I both replicated this with different devices on T-Mobile. He took a look on quantz, and we don't see any errors in the error log, nor the relevant hits in the access log when a request is made from a T-Mobile device. It's as if some proxy server that T-Mobile is using is not able to reach quantz, or there's some strange content being sent around that's breaking somebody.
Let me know if I can help out with the debugging of this one.
Sincerely,
