Working for me.
Can log in, see hubs, device types, smartapps, etc.
Thanks @chuckles
I just tried logging into my account on another computer I have and I was able to log in.
Appears the issues is due to my employer now blocking the site 
I get those messages at home, work, anywhere… All I do is restart the browser, or refresh a few times. Annoying when it happens though. The most annoying thing now is the need to constantly log back in to the IDE.
