No question South Central Azure was down
One more point from the Cedexis data on this outage: US East in Northern Virginia is a heavily trafficked Azure site, but it never quite went entirely off the air. Between roughly 7-8 p.m. Eastern standard time, users trying to access Azure from many different points around the globe suffered a similar fall off in service which took it from at least 95% available to about 5% available. Services continued running but were obviously impaired. South Central Azure, in Dallas, however, did simply go off the air with services zero % accessible, for 80-90 min., during the same period. What was the difference? I could speculate, would rather Microsoft explain.

Why France?
Without being well informed on Azure operations, it's hard to know what some of the Cedexis data means. But another interesting oddity is that of the countries worst affected, France stands out with a deeper and longer lasting trough than other counties. That shows up in two performance charts highlighting country by country results provided by Cedexis, along with a look at the Orange network segment there.

Post a Status update sooner?
So far, Microsoft has tended to be fairly forthright on the fact there was a problem, and later in a post mortem, on the nature of the problem. The timing of the notice on the Azure Status page in this case tended to lag the actual existence of the problem by about 45 min., but in my experience, all service providers operate that way. My interpretation: they try to get on top of the problem or fix it first, supply notice of it when it's becoming obvious to users. Not sure we'll reform them on that point any time soon.
