“We have received feedback from customers that several reboots (as many as 15 have been reported) may be required, but overall feedback is that reboots are an effective troubleshooting step at this stage."
So fuck the headline, the real message is: yes, rebooting is an effective troubleshooting step at the moment.
I don’t know the exact timing of that message in the timeline of the incident, so it could be early “please restart and see if issue persists” or late “something was updated, rebooting will probably help”, I don’t know.
