Lag, but only in Tiragarde Sound?

So right now I’m just doing some Emissary quests for extra gold and what not but I’m getting crazy lag in one area, Tiragarde Sound!

I know it’s not on my end cause I had a second account logged in and went to various other zones and had nothing beyond my normal 40ms latency experience.
I can also take a character who is lagging in Tiragarde Sound, travel to any other zone and the lag magically goes away.
Lately Tiragarde Sound has been like this a lot on Stormrage-US

It’s been an on/off issue all of BFA on multiple servers, with some zones lagging like this despite not showing any changes in my latency, and no performance issues on my end.

It almost feels like the zone is overcrowded, like what happens in the Vale during the world boss fight, despite no active world boss or invasion.
Maybe another zone or shard is spilling over into the rest of Tiragarde?

Anyway, getting sick of lagging on things like the Shell Game and Calligraphy(it actually failed me after moving about 3 yards!) so please pass this along to someone who can investigate the issue.
