Multiple Microsoft 365 services have gone offline on Tuesday (AEDT) with users unable to gain access, the company says in a health status report. Later, the company said it had fixed the issue, without offering any detail as to what had caused the whole thing to collapse.

Rolling back a recent change did not fix the issue as the company initially anticipated it would.

In its latest update, the company said: "Our mitigation strategy was successful in allowing users to sign into the previously impacted services.

"Our internal monitoring has validated this recovery and we have received positive confirmation from customer reports.

"We’ll continue to monitor the service and provide updates on full recovery to remaining impacted users.

The report said: "Users would be unable to access Outlook.com, Microsoft Teams including Teams Live Events, and Office.com.

"Additionally, Power Platform and Dynamics365 properties are affected by this incident."

iTWire has confirmed that the outage is not limited to any one region, with users in Australia also being locked out.

"Existing customer sessions are not impacted and any user who is logged in to an existing session would be able to continue their sessions," the Microsoft notice said.

"We've identified that reverting the recent change did not alleviate impact to Microsoft services as expected. We're working to explore additional options for mitigation.

"Any user may experience access problems for Microsoft 365 services."

Contacted for comment, former NSA hacker Jake Williams said: "It's a good day to plan for how centralising things like Azure Active Directory will impact you in an outage scenario.

"Many who move to AAD do so for security reasons, usually in hopes of protecting confidentiality of their data. But, of course, security includes availability too."

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.
