Microsoft's 365 services have been hit by another outage, beginning at about 2pm EST on Wednesday (5am AEDT Thursday) and affecting the eastern and western coasts of the US.

Users were unable to access their Outlook mail accounts and had problems using Microsoft Teams.

The company said later on that a change to network infrastructure had caused the outage. It said the issue had begun at 6.10pm UTC on Wednesday (5.10am AEDT on Thursday).

It said another update would be issued at 10.30pm UTC Wednesday (9.30am AEDT Thursday).

The 365 services were hit by an outage at the end of September, with the company later blaming a latent code defect — in other words, a software bug — in the Azure Active Directory backend service Safe Deployment Process system for the incident.

In a tweet, Microsoft said about the current outage: "We're investigating an issue affecting access to Microsoft 365 services. Users may see impact to Microsoft Teams, Outlook, SharePoint Online, OneDrive for Business, and Outlook.com."

Questions were raised on Twitter as to whether the company was pushing updates directly to production, without testing.

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.
