Azure Services - Network latencies - South Africa North and South Africa West

What happened?Starting at 10:30 UTC on 14 Mar 2024, customers using Azure Services in South Africa North and South Africa West may experience increased network latency or packet drops when accessing their resources. What do we know so far? We have determined that multiple fiber cables on the West Coast of Africa — WACS, MainOne, SAT3, ACE — have been impacted which has reduced the total capacity supporting our Regions in South Africa. Customers may have experienced potential instability in capacity around this time. In addition to these cable impacts, the on-going cable cuts in the Red Sea — EIG, Seacom, AAE-1 — are also impacting the overall capacity on the East Coast of Africa. These incidents together have reduced the total network capacity for most of Africa's regions. With the current bandwidth demand and network utilization, all services are currently healthy with no issues detected. Working in conjunction with local providers, additional capacity is being added proactively to ensure network stability leading into the South Africa region's business hours on Monday, March 18, 2024. What happens next?Additional updates will be provided to potentially impacted customers through the Azure portal.We will follow up with a preliminary Post Incident Review approximately 72 hours after mitigation.To get notified if a PIR is published, and/or to stay informed about future Azure service issues, make sure that you configure and maintain Azure Service Health alerts – these can trigger emails, SMS, push notifications, webhooks, and more: https://aka.ms/ash-alertsFor more information on Post Incident Reviews, refer to https://aka.ms/AzurePIRs
