Are there any on-going issues right now with SE infrastructure?

Both chat and sites have been experiencing intermittent issues for a few hours. This has been reported on Stack Overflow (main, meta and chat), as well as multiple *.stackexchange sites.

I'd put this down to widespread internet issues with CloudFlare and CenturyLink but rather than failing to connect to SE at all a maintenance message is being shown:

    I believe this page is send to users by the HA-Proxy from SE when the handling of a request takes more than 5 seconds. In other words, every webserver and SQL Server can be happily up and running, only a bit sluggish ....

  • Not sure what is your goal in this question? To change the wording of the message to fit the actual problem? Commented Aug 31, 2020 at 14:56
  • @Shadow The goal is to a) find out if/what the problem was b) encourage work to reduce the likelihood again (if possible) Commented Aug 31, 2020 at 15:10

I was able to verify, this was due to the CenturyLink failure. The CDN was serving the maintenance page as the CenturyLink failure caused it to be unable to reach our origin. Seems obvious now. Sorry, new here so still learning.

    @ShadowWizardWearingMask: Staff bit: "2019-07-31: Stack Exchange employees (users with the staff bit on their account) are now given a special "Staff" marker in their user profile description. Additionally, the old "moderator" user profile mark has a new style." Commented Aug 31, 2020 at 16:06
  • Also, welcome to Meta, and thanks for the explanation!

  • It would be nice to show a staff icon in the (non-expanded) user card, as discussed in meta.stackexchange.com/questions/344019/…, meta.stackexchange.com/a/331658, meta.stackexchange.com/questions/310518/… for example.
