Are you at home?  Who is your ISP?  Can you do a `dig mozcom-cdn.3crowd.mozilla.net any`?
I am at home, my ISP is SFR (second biggest ISP after Orange so if it's ISP related, it may affect a large chunk of the population)

dig mozcom-cdn.3crowd.mozilla.net any

Spoke with engineer at 3Crowd about the issue and relayed data to help with his troubleshooting.

Updated will be made as I get them.

thanks
A triggering event occurred that sent 3crowd destined traffic from some locations to an alternative 3crowd site (Asia).  There appeared to be unrelated issues to 3crowd on the path to this alternate site that was causing the resources to be inaccessible.  The routes have been dropped to circumvent this bad path so things should be available again.

Please confirm things are reachable.

This is now working for me.
Excellent.

dig mozcom-cdn.mozilla.net

;; global options: +cmd
;; connection timed out; no servers could be reached
and now it is working again. I am not sure what I should do about that because this happens too often and is hard to reproduce...
The problem you are resenting is unrelated to the problem of the original description.  For example in Comment 13 "connection timed out; no servers could be reached" suggests more an issue between your client and your configured DNS and not 3crowd.

In the future please open a new bug providing the output of `dig mozcom-cdn.3crowd.mozilla.net any`, your location, your configured DNS, and time of the query that will help.
