Hi all, I’m Shohei from engineering.
I’m writing to let you know that this has been fixed as of 15:01 UTC on 2/14/2025. We’re sorry for the trouble this has caused you.
- We have many edge locations across the globe, and we have multiple in South Korea as well. Specifically, we use AWS Global Accelerator to operate our Anycast network (related blog post)
- On 2/7/2025, the AWS Global Accelerator team made routing optimization changes for edge locations in South Korea. This caused a subset of traffic from South Korea to be incorrectly routed to our kix1 (Osaka, Japan) region
- This impacted a subset of traffic for ASN 9318, 4766, 17858, 9644, 17853, 3786, 9316
- The issue was mitigated as of 15:01 UTC on 2/14/2025, as we made further changes to correct routing in South Korea.
