I’m seeing the same issue in Boston on Xfinity as well.

It’s not limited to one site. A wider range of China-based services seems affected on my end, including multiple Chinese websites and game-related servers. Some sites load extremely slowly, and some services are effectively unusable even though the general internet is otherwise working normally.

So this does not look isolated to San Jose.

Same problem here in Denvor, I tried to ping my Xfinity assigned IP and it is unreachable globally

Same in Seattle. Starting from the evening of March 2nd (PST), I have been experiencing significant routing issues to services hosted in China or utilizing specific Asian CDNs. The symptoms are very specific. I can download updates and log in to my account (HTTPS), but I cannot enter the actual game screen. The connection to the game’s real-time communication servers (likely UDP) fails consistently.

Same issue in Colorado. Access to Mihoyo's Chinese website and its games is unavailable.
