EU servers are not playable after Friday, Jun 13th maintenance

EU servers are not playable after Friday, Jun 13th maintenance.
Symptoms:
1) Often "Abnormal Disconnection" errors, seems caused y server-side fall of the game instance. Causes loss of map, progression on this map, all map content is lost (i.e. map with bosses, breaches and so on turns into simple empty map, like it was map fail). Can happen immediately on first load of the map.
2) Terrible lags, instability, desyncs all over the board.

Don't know, what happened there, but it definitely caused by changes made during maintenance on Friday.

I can second this, since start of new poe1 league, poe2 is unplayable. Attempting mapping is just throwing away maps/towers/nexuses rn...

After 1 to 2 min of lag free gaming, network just goes ballistic out of nowhere. You d/c and when you log back in, portals are gone, your waystone is gone, and the map just says 'map attempted'.

This totally bricks the game. How are we supposed to sustain maps like this?

So I got into Viridian woods, the map that gives new Atlas points, I was like wooooow so nice, than it got disconnected, and it said Map failed when I logged back in. This is the shittiest thing that happened thus far, and there were a lot. It would be kinda ok if it got disconnected but it gave you a chance to continue where you left off, but nooooooo. MAP FAILED. I beg to differ, your servers failed. Can you at least this super annoyance into a mild annoyance? Is that too much to ask?
