Experiencing massive latency issues seemingly at random

Started happening today, when loading to some zones, instead of the average ~20ms i'm usually getting within the scope of my nearest datacenters (EU Frankfurt/EU Milan), I began getting highly volatile 100-3000ms, occasionally soaring to 30-40k ms at which point it 'played back' what the server was sending and my character inevitably died (SC Abyss campaign so no big issue yet)

A bit of workaround looks to be to keep spawning new instances of that zone until i get one which has the ~20ms at which point i'm able to progress normally.

Based on my previous work experience (and no knowledge whatsoever of GGG's server infra and setup), if the instances are containers and orchestration is some flavour of K8S, you might have an issue with node labels and nodes in different datacenters might be serving those workloads or loadbalacing might be iffy or some AZ in those EU datacenters might be on the fritz and i'm landing on those nodes (but this should normally not possible so pure speculation from my side)
