ISP: Telia
Country: Sweden
When does the problem occur: Experiencing freeze lags for up to 5-10 seconds as well as occasionaly high latency/action delay randomly troughout most of the day, but more intesified during evening/prime time.
Especialy evening time(EU) it can get so bad that loading between zones can last for 10 minutes, happens both during instanced runs and outside of.

Have tried every possible soultion on my own as well as contacting my ISP without anything helping.
Even tried with connecting trough a paid VPN, which while stopping (most of)the random 5-7sec lag spikes instead made the game unplayable trough too high MS/latency and occasional 90k error.


Edit note: I did not have any issue whatsoever until about 10 days ago, and its been getting worse ever since.
