Hinet is a Chinese ISP and is the last hop where I can get a trace. This correlates with various news reports mentioning that various Chinese ISPs have cut off Taiwan in retaliation to a visit of a US representative in Taiwan.

It's interesting to see just how much geopolitics I get to see just by reading my error logs on ITSB.

The generation has failed again today, showing a very similar traceroute. I guess this issue is likely to occur some more, since de-escalation likely will never occur…
