Amsterdam many DC - Act 6 Town bad performance

Server: Amsterdam
Merc League

Played last 2h (sometimes).
Had about a dozen dc.

Act 6 Town has very bad performance, and every portal brings you back to it.
Stash management in town is even worse.

Yesterday playing was ok.

Delve this league was unplayable!
2-3 days ago I tried 1st (!!) Delve but died 2x without any chance of reaction.
Yesterday with 10 levels overleveled I mnanaged to do 1st delve area barely.
