On July 30th at 13:28:59 UTC, customer API traffic routed to our Singapore Data Center started to experience increased latency or timeouts due to issues affecting our Content Delivery Network (CDN) provider.
Our CDN provider experienced a localized outage in the Asia-Pacific region.
This caused some customer API requests originating from this region to the api.nexmo.com and rest.nexmo.com endpoints to experience increased latency or timeouts.
Our systems first alerted us of a potential problem at 13:34:00 UTC and we were able to confirm the root cause and mitigate any impact at 14:07:00 UTC.
Improved alerting and monitoring.
Review our CDN redundancy approach to minimize the disruption of similar events may have to our customers in the future.
