Nice to see another fellow ffxiv player here Recently returned to hometown and realized Unifi's ping is just straight up shit, especially during "peak hours" like 9-11pm. No problems whatsoever when I was using TIMES.
And after much googling it really looks like a routing problem on TM's end .... sadly I don't think there is much can be done and just hope that TM gets their shit together soon.

A few weeks ago during the undersea cable drama when even TIMES was affected, using mudfish VPN actually helped a lot. Sadly even mudfish VPN cant save from TM's incompetence.
