I’ve typed https://perf.cloud.unity3d.com/ in my browser for a week now and it stopped working. Do you guys have the same problem?
@Victor_Kallai Hmm, the site seems to be up from here and there http://downforeveryoneorjustme.com/perf.cloud.unity3d.com
Are you still having this issue?
It just does not work in Chrome for me. I’ve tried with Firefox, and it works just fine. Also, for everyone else from my team it works just fine, even in Chrome. 
This is some really weird bug.
Sometimes I’ve seen ad blockers block sites that have things like “ad.js”. Could this be the case?
Not working for me either, on Chrome 46.0.2490.80. Just a white screen - the same for if I try to go to the general developer dashboard. Works fine in Firefox.
Sadly, if a project is loading for your coworkers in chrome and not for you, it makes it pretty hard for us to pin down. If it works in Firefox for you, it points to something with your chrome install or plugins. I really wish I had a better answer.
If particular project doesn’t load in either Firefox or Chrome, then it could be server side. One issue we have seen is a large number of exceptions causing the request to time out. I think I have optimized the timeout issue, so if it was that, it should be solved.
If you find a way for us to reproduce your error, let us know and we will be happy to fix it. Without such a means, I’m not too sure on what we can do; which is a pretty poor answer. If you have any ideas let me know and we can try them.
