Concurrent players on Steam right now. A real outage pulls this number down within minutes, so a normal count alongside a flat report count usually means the problem is on your end.

About ACE COMBAT 8: Wings of Theve's servers
ACE COMBAT 8: WINGS OF THEVE is Bandai Namco Entertainment’s air-combat game, developed by Bandai Namco Aces. On Steam (app 2288340) the store page lists release as October 1, 2026, with an early-access window opening on September 29 per Bandai Namco’s product page. It is also listed for PlayStation 5 and Xbox Series X|S on Bandai Namco’s product page. Steam showed about 32,800 players at the time of this page’s last check. It includes a campaign and ACE COMBAT ONLINE, a cross-play mode with its own progression.
There is no dedicated status dashboard. During launch week the official @AceCombatGames account on X and the Steam news hub carried the notices we found: an ST-3100001 error post, two maintenances to clear penalties, and a PC crash report thread. If reports on this page spike with no matching notice from Bandai Namco, that is the clearest sign of an unannounced problem.
Maintenance, queues, and real outages
Three different things get reported as "ACE COMBAT 8: Wings of Theve is down," and only one of them is an outage. The chart above is the fastest way to tell them apart, once there's data on it:
A real outage
Reports spike hard within an hour, then decay as the problem is fixed. Nobody announced it in advance.
Scheduled maintenance
Reports climb steadily and stay flat for the length of the window, because everyone hits the same wall at the same time and keeps hitting it.
A login queue
Matchmaking/login reports climb while server-connection reports stay low, and a Steam player count (if shown above) holds flat instead of dropping. The servers are up and full, not down — waiting is the only fix.
Announced maintenance would show up at the studio's own status channel before it shows up here.
If it's only broken for you
Most "is it down" moments aren't outages. Work down this list before assuming the servers are the problem — it's ordered by how often each one turns out to be the answer, not by how easy it is.
- 01
Check the report count above first
It costs nothing and it settles the question. A flat report count means other players are getting in fine, and everything below is worth your time. A spike means it isn't you, and none of it is.
- 02
Verify the game files
In Steam: right-click ACE COMBAT 8: Wings of Theve → Properties → Installed Files → Verify integrity of game files. A partial patch is the single most common cause of a game that launches and then fails to connect.
- 03
Restart the whole chain, in order
Game, then your launcher/Steam, then your router. People almost always do the first and skip the third — a stale router NAT table produces exactly the symptom people report as "servers down."
- 04
Rule out a VPN or restrictive network
A VPN fails matchmaking far more often than it fixes it, and so does a corporate or campus network that blocks the UDP ports a game server needs. If you're on a network you don't administer, that's the likely answer.
- 05
If it crashes rather than fails to connect, treat it as a crash
A game that starts and then dies, rather than never connecting, is usually a local fault — most often graphics drivers or overlay software, not the servers.
ACE COMBAT 8: Wings of Theve server status: common questions
Is ACE COMBAT 8: Wings of Theve down right now?
As of 15:50 UTC, 0 players have reported a problem in the last 15 minutes — counted as people, so repeat taps from one person don't inflate it. This page updates on every load.
Does Bandai Namco publish an official ACE COMBAT 8 status page?
No dedicated status dashboard was found. Server problems with ACE COMBAT ONLINE have been announced on the Steam news hub for app 2288340 (for example the "About Error Code: ST-3100001" post) and on the official @AceCombatGames account on X, which posted the mission-results fix notice and both penalty-clearing maintenance windows in launch week. Check those two first.
When is ACE COMBAT ONLINE maintenance scheduled, and where is it announced?
No fixed recurring schedule has been published that we could find. What's been announced so far is ad hoc, on the official @AceCombatGames account on X: a maintenance on September 29 to clear the penalty status of players caught by a mission-completion problem, and another on October 1, ending at 13:00 CEST (4:00 AM PDT), to clear penalties applied because of matchmaking errors. After that one ended, the account said the servers were available again and that it was still investigating the matchmaking errors.
ST-3101004: connection lost after a mission →What server regions does ACE COMBAT ONLINE use, and can I pick one?
Bandai Namco has not published a region list or a region selector that we could find, so we don't list one. Steam Discussions reports of connection timeouts come from players in Europe and Asia, which only shows the problems are not limited to one region.
ST-3100001: the connection-timeout error →Why can't I enter ACE COMBAT ONLINE, and is it my connection or the servers?
It can be either. Bandai Namco's own post says ST-3100001 appears when communication with the game server is lost, and asks players to check that the Windows clock is synchronised. ST-4000906 appears when entering ACE COMBAT ONLINE, and a player in one Steam thread said it was affecting "pretty much everyone"; no official statement has been seen on it.
ST-4000906: what's known so far →Does ACE COMBAT 8 have cross-play?
Yes for ACE COMBAT ONLINE. Bandai Namco's product page describes it as a cross-play mode across PlayStation 5, Xbox Series X|S and PC (Steam), and Steam lists the game as "Cross-Platform Multiplayer". It has its own progression, separate from Campaign Mode.
If ACE COMBAT ONLINE is down, can I still play the campaign?
Bandai Namco describes ACE COMBAT ONLINE as a separate mode with a separate progression system, so an online problem is not the same as a campaign problem. We have not verified whether the campaign requires a connection. Crashes that players report in the campaign, such as "Error 01", are reported as local engine crashes rather than server outages.
Error 01: crashes and the fixes players report →What does Bandai Namco say about crashes on PC?
On October 2, 2026, Bandai Namco's official Steam announcement "PC Crash Report Thread" asked players to post a detailed crash report (error code, PC specs, Windows version, reproduction steps) in the thread. It did not name a cause or a specific fix in that post. Players' workarounds for Error 01 are collected on this site's Error 01 page.
Error 01 (UE crash): what's reported →Incident history
Auto-logged from player reports over the last 30 days. An incident is a run of hours with at least six different players reporting in each, the same signal the verdict above responds to — so one frustrated player pressing a button repeatedly can never put an incident on this list.
No incidents logged in the last 30 days.
