I haven't seen any maintenance reports but I'm getting some weird....hiccups today. I swear it's like there's some kind of system gremlins tinkering in the system!
I've gotten these....and some 'Bad Gateway's....and clicking of a mouse but nothing moves.
Is there some kind of 'clearing of cookies' you can do for Workfront?
There is a "Empty cache and hard reload" option in Chrome when you bring up the Dev tools and right click on the referesh icon. This is really the best and only thorough way to refresh your (Chrome) browser. It does not delete cookies though. I would save that for last resort since it resets your site based preferences.
Usually, when a site just seems 'glitchy", it's one problem causing multiple symptoms. It could be anything from a database issue to a connectivity issue inside or outside the host. Sometimes doing a hard reset helps though so it's worth a try.
This one is kinda funny as I've been seeing this since NWE launched 2 years ago!
