Unbearable server lag since yesterday

[MegaMage]

Hello,

I am on Lamia server. Since yesterday evening there has been a consistent unbearable delay in game. It makes the game completely unplayable as everything in game comes to a complete stop which then fast forwards to catch up. It happens every few seconds.

I have read online that this may be due to Comcast <> SE's servers.

Can anyone confirm this?
Anyone have any guidance on what I might do to curtail this issue?

I have re-issued myself a new IP, restarted modem & router, etc. and nothing has any effect. I have Gigabit internet, connected through wired ethernet. I experience no issues with lag in any other game, streaming service, website, etc.
