Microsoft has said it had fixed the underlying cause of a service disruption linked to an earlier network capacity upgrade, though some customers and regions were still awaiting restoration.
The company attributed the outage to a fault introduced during that upgrade that emerged after a more recent network change, and said the incident was unrelated to cyber activity, AI or agents.
It reported broad recovery across its services and said it had restored them in stages given the scale of demand, checking stability at each stage, an approach it acknowledged had taken longer.
The company apologised to customers and partners for the disruption and said it would publish a full post-incident report after completing its review.
