thanks a lot for the report. It is a bit problematic to debug it outside of China :-( Are you please able to find which exact request blocks the page loading (using developer tools in your browser)? Because as I know we perform all google requests in an asynchronous manner, which should not block page loading/rendering if these services are not available.
Thanks a lot in advance
So it seems the problem has nothing to do with google services.
The very long load of avatar image is really strange, we use Akamai Content Delivery Network for static.jboss.org domain to improve load times around the world. I have no idea why this is a problem on your location :-(
batch.js if some mechanism in jira which allows to join more small js files provided by more componenets into bigger one, it depends on appended params what is exactly returned in it. And yes, it is strange why load of it is blocked until avatar image load.
BTW is this bad behavior repeatable in Chrome (is the problem with same requests when you reload the page), and is it also repeatable in another browser (eg. Firefox).
