“Has any one started getting discussions with their CIO/CEO about going back again to an in-property mail server? I advocate for it”

Provided the scale of its consumer foundation and with a agreement really worth up to $10 billion in the bag to run the back again-conclusion of a superpower’s armed forces, Microsoft could want to start off wondering about how it can build a staging technique for its Azure cloud that allows it to deploy adjustments and reliably roll back again these adjustments when things split.

(We know, it is simple to say so from a protected distance…)

Redmond was at it once again late Monday, knocking an (apparently sizeable) “subset of consumers in the Azure Community and Azure Authorities clouds” offline for 3 several hours with swathes of consumers globally encountering errors carrying out authentication operations multiple expert services have been affected, together with Microsoft 365.

The corporation blamed the difficulty on a “recent configuration transform [that] impacted a backend storage layer, which caused latency to authentication requests.” (Read through, consumers could not login to Teams, Azure and a lot more for several hours for the reason that of the snafu).

A whole root lead to evaluation is pending. (We will update this piece when we see it). The blockage was felt for consumers from 22:25 BST on Sep 28 2020 to 01:23 BST.

The difficulty comes a fortnight after a protracted outage in Microsoft’s Uk South region induced by a cooling system failure in a facts centre. With temperatures mounting, automated units shut down all community, compute, and storage sources “to secure facts durability” as engineers rushed to acquire handbook management.

Before this thirty day period in the meantime Gartner mentioned it “continues to have worries associated to the overall architecture and implementation of Azure, even with resilience-concentrated engineering initiatives and improved services availability metrics during the previous year”.

Microsoft Azure CTO Mark Russinovich in July 2019 mentioned that Azure experienced formed a new Excellent Engineering workforce within his CTO place of work, functioning alongside Microsoft’s Web page Reliability Engineering (SRE) workforce to “pioneer new methods to deliver an even a lot more trusted platform” pursuing client issue at a string of outages.

He wrote at the time: “Outages and other services incidents are a problem for all general public cloud vendors, and we continue to make improvements to our being familiar with of the advanced approaches in which elements these as operational procedures, architectural patterns, components troubles, program flaws, and human elements can align to lead to services incidents.

Stranger things have took place.
