On both the mozillaignite ( and webmaker ( projects we've recently been experiencing irregular login failures - as of around yesterday afternoon (2pm, GMT).

After a bit of digging and adding in extra logs we were able to find the following error being thrown:

django_browserid.base:INFO Verification URL: :/projects/mozilla/ignite/mozilla-ignite/vendor-local/src/django-browserid/django_browserid/
django_browserid.base:DEBUG Failed to decode JSON. Resp: 500, Content: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "">

<h2>Service Unavailable</h2>
<p>The service is temporarily unavailable. Please try again later.</p>


Both have recently been updated to use the new playdoh - so that django can be deployed out if it, fixing this issue (

Setting as major as both projects being effected are hoping to be deployed next week, and also as this may be an issue on other sites using browserID and django-browserID. is Mozilla Services. Moving...

Thanks Shyam - that was the one thing that I wasn't sure about :)
You're welcome Ross. I've poked the services ops folks on IRC as well, if this is incorrect, they'll move it to the right place and look at it.

I think this is probably fixed now.  The verifier pool in scl2 had all backends marked as draining for some odd reason, so when GSLB gave you scl2's IP address for, /verify calls would fail.

We need to start QAing the verifier service before we undrain a datacenter during a push.

Yes. I agree.
Seems like I need to update our Test Plan to add a section for Prod push specific stuff.
Probably something that could be automated...

Filed bug 753828 to monitor zeus pools so we'll catch this before undraining a datacenter in the future.
Should be covered by a script that :jrgm has.
Also, running it once per colo per Prod push should be enough to verify everything is working as expected (getting a 200 back rather than a 500).

Marking as Verified since we appear to have everything in place, including tests for Prod.
