Hi,

We're experiencing the above error when trying to access any page on nbviewer, even though the status page lists everything as operational.

About a year ago we experienced the same issues which seemed to be resolved for quite some time, see closed issue 607.

The status page has been updated now, and @minrk is investigating.

The 503 error typically happens when there is an issue with the operation of the hosted public instance. As nbviewer.jupyter.org seems to be healthy right now, I'm going to close this as resolved. If there's a particular action you're taking that repeatedly leads to 503 errors, please comment to let us know.
