Hello Microsoft Team,

We experienced a service interruption impacting Azure Virtual Desktop users across multiple host pools (RBKC and Sandwell) on 18 June 2026 between approximately 20:30 and 21:00 IST.

Symptoms

• Users were unable to connect using Windows App.
• Error received:

"This computer can't connect to the remote computer. The remote computer did not send an expected activation packet in time allotted."

Environment

• Azure Virtual Desktop
• Region: UK South
• Multiple host pools affected simultaneously
• Multiple session hosts affected
• Users across different locations impacted

Observations

• Session host VMs remained online.
• Direct VM access remained available.
• Service recovered automatically after approximately 15-30 minutes.
• No configuration changes were performed during the outage.
• No current Service Health incidents visible related to Azure Virtual Desktop.

Request

Please investigate whether there were any:

• Azure Virtual Desktop Broker issues

during the above timeframe affecting UK South.

Please provide root cause details and confirmation whether this was a Microsoft-side service event.
