Not Blizzard’s fault for once,
We’ve confirmed the degraded network performance in our first update is due to a cable cut, which occurred at approximately 18:00 UTC, April 19. This cable is located just west of Singapore and impacts the cabling system connecting 17 countries from Singapore to Europe.
As a result of multiple subsea fiber faults between Europe and Asia regions, the issues appear to be a direct consequence of congestion resulting in packet loss and increased latency connecting to the SGP1 region. Customers in the Asian region are having difficulty reaching DigitalOcean resources located in Amsterdam (AMS2, AMS3), London (LON1), and Frankfurt (FRA1).
Can see the latency happening on other services as well.
