Pokémon Champions Maintenance September 9 ran from 02:00 UTC to around 06:00 UTC on September 9, 2026, and the scheduled work is now complete. In the UK, that was 03:00 to around 07:00 BST. The maintenance took the game offline while the Version 1.2.0 update and Regulation Set M-C changes were deployed.
The original Pokémon Champions Maintenance September 9 notice described 06:00 UTC as the planned finish, and the completion notice later confirmed that servers returned at approximately that time. Players who are trying to connect after the window should therefore make sure the new update has installed rather than waiting for maintenance to end again.

Why Did Pokémon Champions Need Maintenance?
The Pokémon Champions Maintenance September 9 window coincided with the launch of Regulation Set M-C. The completed update added the M-C Pokémon and held items, applied battle-balance adjustments and introduced new battle tools.
The update also changes competitive legality. Regulation M-C began at 02:00 UTC on September 9 and is scheduled to remain active until 01:59 UTC on December 2, 2026.
What Was Added During Maintenance?
Alongside the Regulation M-C roster, Pokémon Champions Maintenance September 9 added six Mega Evolutions: Mega Absol Z, Mega Salamence, Mega Garchomp Z, Mega Lucario Z, Mega Golisopod and Mega Baxcalibur.
Version 1.2.0 also adds Battle Log, which lets players review actions from the current battle, and Selection Support, which displays team-selection support information based on battle data during the selection screen.
What Balance Changes Went Live?
The Pokémon Champions Maintenance September 9 patch removes Pound from Politoed’s available movepool and removes Mirror Coat and Metal Burst from Archaludon. Slash becomes usable, while Wish and Strength Sap both drop from 12 PP to 8 PP.
Those are meaningful rules changes rather than cosmetic patch notes, especially for players moving directly from Regulation M-B teams into M-C.
What Happened to Battles When Maintenance Started?
Pokémon Champions warned that battle results would not be reflected if a battle was still in progress when Pokémon Champions Maintenance September 9 began. That warning was part of the official downtime notice.
If a match around 02:00 UTC appears missing, that is consistent with the maintenance rule rather than evidence that a new connection problem has appeared after the servers returned.
Are the Servers Back Now?
Yes. Pokémon Champions Maintenance September 9 is complete. If your game still says it cannot connect, check for Version 1.2.0 first, then troubleshoot your local connection.
The official maintenance notice confirms the scheduled Pokémon Champions Maintenance September 9 window and the warning about in-progress battle results.
