I think this is something that's probably just never been operational for mozilla.org, and is only coming up now because of the mozilla.com redirect to it. I'll look into enabling this.

This should be fixed. The Phoenix Zeus cluster was already doing this, but the SJC one was not. Depending on where a user was at, they may or may not have been affected by this.

There are a couple things worthy of noting:

1) By default Zeus doesn't both compressing things under 1k.

2) It operates based on MIME types, so if you notice something not getting compressed that you think should be, please let us know and we can add it to the list. The default list is pretty sparse (text/html, text/plain, application/x-javascript, and text/css), but should cover the major cases.

3) This has to be set in at least 4 places- there are separate HTTP and HTTPS services, and each live in both SJC and PHX. There might be others, so if you notice something not getting compressed as per (1) and (2) above, please let us know. It could be that there's some other location I'm not aware of that needs updated.
