Possibly, so please do send them (through support) if it's not too much trouble.
It took me a bit of poking to figure out how to do it, but effective 3:40pm MST, I just cut off the s3 for your downloads if your client id is in this list:
18167, 124955, 17582, 5945, 37624, 38156, 21404, 84674
Note I haven't modified the code, just did a little backend database trickery, so any new uploads you do will get transfered to and served from s3 as normal.
Please let us know if this causes any noticeable change for you, good or bad. This is just a test, not a fix--we need to leverage the cloud for low-cost scalability.
