Maintenance Schedule

Aion 2's global servers go down for weekly maintenance every Tuesday at 22:30 PST (Wednesday 07:30 CET), for 4 hours 10 minutes on average over the six since launch. All six with NC's announced length and patch, the start and return in seven time zones, how far ahead NC posts the notice, what resets with it, the extra maintenances, and our call for Nov 17.

Aion 2's weekly maintenance starts every Tuesday at 22:30 PST, which is 07:30 CET on Wednesday, and the six since the Oct 5, 2026 launch were announced at 3 hours to 5 hours 30 minutes, 4 hours 10 minutes on average. The last one, on Nov 10 (PST), was set at 4 hours 30 minutes and NC has marked it completed (NC on Steam, read Nov 11, 2026); the next falls on Tuesday, Nov 17, and NC had not posted its notice when this page was written.

Next: a live countdown to the next maintenance and reset on your own clock, where to look when the game is down outside this window or what each of these patches added.

Every weekly maintenance since launch

Tuesday (Pacific date)	Start	Announced length	The patch it carried
Oct 6, 2026	23:30 PDT, 08:30 CEST	3 hours 30 minutes (Asia 5 hours 30 minutes)	Fixes, drop rates and shop changes
Oct 13, 2026	23:30 PDT, 08:30 CEST	4 hours	Halloween shop, Sorcerer and Spiritmaster fixes
Oct 20, 2026	23:30 PDT, 08:30 CEST	5 hours 30 minutes	Hard Krao Cave and Draupnir, the Ariel board
Oct 27, 2026	23:30 PDT, 07:30 CET	4 hours 30 minutes	Hard Urugugu Canyon and Vakron Sky Island, more base HP
Nov 3, 2026	22:30 PST, 07:30 CET	3 hours	Ludra, Chaotic Outer Reshanta
Nov 10, 2026	22:30 PST, 07:30 CET	4 hours 30 minutes	Hard Fire Temple and Ferocious Horn Den

Each length is the one in NC's notice for that week, read on Nov 11, 2026: Oct 6, Oct 13, Oct 20, Oct 27, Nov 3 and Nov 10. The six add up to 25 hours, which is where the 4 hours 10 minutes comes from; the middle of the six is 4 hours 15 minutes. NC edits the same notice to "(Completed)" when the servers return and does not state the minute, so these are planned lengths, not measured ones. Only one notice gives a region a longer window: on Oct 6 the Asia servers were down 5 hours 30 minutes, two hours more than the rest.

The length does not follow the size of the patch. The shortest window, three hours, carried the biggest update so far, the return of the Ludra raid, and the longest carried two Hard dungeons.

The clock time never moved

The start reads 23:30 in October and 22:30 in November only because North America left daylight saving time on Nov 1, 2026. In both months it is the same instant, 06:30 UTC on Wednesday. Europe's hour did move, from 08:30 CEST to 07:30 CET, when Europe changed its clocks on Oct 25. Since Nov 1:

City	Maintenance starts	Back after 3 hours (shortest)	After 4 hours 10 minutes (average)	After 5 hours 30 minutes (longest)
Los Angeles	Tuesday 22:30	Wednesday 01:30	Wednesday 02:40	Wednesday 04:00
New York	Wednesday 01:30	04:30	05:40	07:00
Sao Paulo	Wednesday 03:30	06:30	07:40	09:00
London	Wednesday 06:30	09:30	10:40	12:00
Berlin, Paris	Wednesday 07:30	10:30	11:40	13:00
Dubai	Wednesday 10:30	13:30	14:40	16:00
Tokyo	Wednesday 15:30	18:30	19:40	21:00

All five regions go down together, so the window that costs a North American player sleep costs a player on the Asia servers, which are hosted in Japan, the late afternoon and early evening of Wednesday (Servers).

When NC tells you

NC posts the notice on its announcements board and on Steam the day before or the morning of the maintenance. By the times Steam shows on the six notices, four went up about 19 hours before the start (Oct 6, Oct 27, Nov 3 and Nov 10), one about 25 hours before (Oct 20) and one about 29 hours before (Oct 13). Every one of them says the schedule and details "are subject to change at any time" and that changes come as an update to the same notice, so the notice itself is the page to reload. The patch notes are a separate post, and all six went up as the maintenance began or within three hours of it.

What resets with it

0:03 The game's week turns over with this maintenance. Spid, three days into Advanced Access on Oct 3, 2026, tells players starting on the Monday launch that the weekly reset comes on Wednesday and leaves them two days to use up the week's entries. The shop follows the same clock: NC's patch notes end each skin lineup "before maintenance" on a named Wednesday (Cash Shop and Cosmetics), and the Daily and Weekly Checklist lists what to finish before the servers close.

The maintenances that are not weekly

Launch. The servers closed for eight hours from 22:00 PDT on Sunday, Oct 4, 2026 to end Advanced Access and open the free launch (NC on Steam).
Temporary maintenance. Ninety minutes on Sep 30 for a quest bottleneck and ninety on Oct 8 for server stabilization, then two and a half hours per region for the clock changes: Europe on Oct 24 (PDT), NA East on Oct 31 and NA West on Nov 1 (Europe, NA East, NA West). The next clock changes are in March 2027.
Platform services. NC's account systems have their own windows, and the game stays up through them: 30 minutes on Oct 13, and 3 hours 40 minutes from 12:00 PST on Nov 10, when account creation and the Account and Security pages were closed (NC on Steam).

What we expect on Nov 17

We think the maintenance of Nov 17 (PST) starts at 22:30 PST like the two before it and is announced at 4 hours 30 minutes or less. Five of the six so far were, and the one that ran longer came with the first Hard dungeons, a kind of patch NC has shipped twice since inside 4 hours 30 minutes.

Confidence: Likely. Check by: Nov 18, 2026.
