Google Adwords seems to have broken CSS for a couple of hours already

It looks like this right now: https://dl.dropboxusercontent.com/u/14185619/adwords.png (checked on 3 different IPs and the image is generated by https://screenshotmachine.com/ )

Makes me wonder how this can effectively be monitored when also doing A/B experiments.

Probably because they are doing A/B experiments with their new layout for adwords: http://imgur.com/a/gopki
