Azure has identified the root cause of the issue impacting services in the Switzerland North region. A recent deployment introduced a malformed certificate prefix that disrupted connection authorization.

Microsoft has rolled back the faulty deployment and is seeing recovery across impacted services. They are continuing to monitor traffic and service stability, with full mitigation expected by 05:30 UTC.

We will keep monitoring the situation and share another update once full recovery is confirmed.
