Is Azure Synapse Analytics down?
Current Azure Synapse Analytics status is UP

We are currently investigating an issue with Azure Storage. Azure KeyVault and other Azure services dependent on Azure Storage may experience intermittent failures and degraded performance.
Current Status: We have identified that a spike in incoming traffic has caused components of our service to become unable to process incoming requests. This impact is limited to a single stamp in this region. We are currently in the process of performing recovery actions to alleviate customer impact. 
Further updates will be provided in 60 minutes, or earlier if events warrant.

Impact Statement:
Starting around 20:19 UTC on 7 February 2023, a utility power surge in the Southeast Asia region tripped a subset of cooling units offline in one of the Availability Zones. While working to restore the cooling units, temperatures in the datacenter increased and we have proactively powered down a small subset of compute and storage units to avoid damage to hardware and reduce cooling system load.
All impacted storage and compute scale units are in the same datacenter, within one of the region’s three Availability Zones (AZs). Multiple downstream services have been identified as impacted.
Current Status – 03:30 UTC
We are continuing to focus our efforts on mitigation for services which were impacted due to this incident. The core storage and compute services restoration have been completed successfully.
We have several other key services fully recovered and for some of which we are still working on post recovery checks. We are closely monitoring the datacenter metrics for storage and compute resources which continue to show healthy thresholds.
We will continue to provide updates as we have further progress towards service restoration. We will share our next update in 2 hours or as events warrant.

Issue Summary: Starting around 20:19 UTC on 7 February 2023, a utility power surge in the Southeast Asia region tripped all of the chiller units for one datacenter offline. While working to restore the chiller units, temperatures in the datacenter increased so we are proactively powering down compute, storage and networking resources to avoid damage to hardware. All impacted infrastructure is in the same datacenter, within one of the region’s three Availability Zones (AZs). Downstream services that have been identified as impacted include Azure App Services, Azure Backup, Azure Cosmos DB, Azure Database for MySQL & flexible server, Azure Database for PostgreSQL & flexible server, Azure Log Analytics, Azure Red Hat OpenShift, Azure Search, Azure SQL Database, and Azure Virtual Machines (VMs).
