Starting at approximately 16:00 UTC, we began experiencing Azure Front Door issues resulting in a loss of availability of some services. We suspect that an inadvertent configuration change as the trigger event for this issue. We are taking two concurrent actions where we are blocking all changes to the AFD services and at the same time rolling back to our last known good state.
We have failed the portal away from Azure Front Door (AFD) to mitigate the portal access issues. Customers should be able to access the Azure management portal directly.
We do not have an ETA for when the rollback will be completed, but we will update this communication within 30 minutes or when we have an update.

"We have initiated the deployment of our 'last known good' configuration. This is expected to be fully deployed in about 30 minutes from which point customers will start to see initial signs of recovery. Once this is completed, the next stage is to start to recover nodes while we route traffic through these healthy nodes."

At this stage, we anticipate full mitigation within the next four hours as we continue to recover nodes. This means we expect recovery to happen by 23:20 UTC on 29 October 2025. We will provide another update on our progress within two hours, or sooner if warranted.

Would this also be true for electrostatic speakers as well? Though would probably would require greater gain/amplification or, potentially the application of some kind of bias voltage for the capacitive diaphragm of the speaker.
Just speculation based on the shared operating principal with condenser microphones
With bias power, I think an electrostatic loudspeaker turns into a condenser microphone (a thing that provides varying capacitance in response to changes in pressure).
I don't think that electrostatic loudspeakers all require bias power, so it's not quite as simple as using a dynamic loudspeaker backwards is.
It is a neat idea, though. A big, flat-panel microphone would be interesting to play with.
You can use a window or any large panel as a microphone without even touching it by observing its vibrations.
You can bounce a laser off it, or even go fully passive using a camera with some sensitivity tricks: I recall a paper that reconstructed a remote conversation by watching a houseplant through a window.
As best as I understand it, they are trying to add more structure to the data lake, and optionally ACID compliance, so that datawarehouse tools can talk to the lake directly.
These are core principles that are taught to Emergency Managers in the Swarm Leadership method [0].
Unity of mission – it was for these leaders, Save Lives!
Generosity of spirit and action – these leaders and people across the community were willing and eager to help one another.
Stay in your lanes, doing your job, and help others to succeed in theirs. How can I make you a success?
No ego – no blame. No one took credit for their success together. No one pointed fingers when problems arose.
A foundation of trusting relations – these leaders knew and had confidence in one another.
