The Honkai Star Rail 4.3 update arrives the way every HoYoverse patch does. Servers go down first, the build deploys, and the new version goes live once maintenance wraps. For 4.3, the downtime ran for about five hours, ending the moment the update became playable on June 1, 2026.
HSR 4.3 maintenance start and end times by region
The maintenance happens at the same moment everywhere. Only your local clock changes. Players in the Americas saw their servers close on May 31, while Asia, Oceania, and most of Europe crossed into June 1 during the window. Here is the full breakdown.
| Time zone | Start | End |
|---|---|---|
| PDT (UTC-7) | May 31, 3:00 PM | May 31, 8:00 PM |
| MDT (UTC-6) | May 31, 4:00 PM | May 31, 9:00 PM |
| CDT (UTC-5) | May 31, 5:00 PM | May 31, 10:00 PM |
| EDT (UTC-4) | May 31, 6:00 PM | May 31, 11:00 PM |
| UTC | May 31, 10:00 PM | June 1, 3:00 AM |
| BST (UTC+1) | May 31, 11:00 PM | June 1, 4:00 AM |
| CEST (UTC+2) | June 1, 12:00 AM | June 1, 5:00 AM |
| MSK (UTC+3) | June 1, 1:00 AM | June 1, 6:00 AM |
| IST (UTC+5:30) | June 1, 3:30 AM | June 1, 8:30 AM |
| CST China (UTC+8) | June 1, 6:00 AM | June 1, 11:00 AM |
| JST (UTC+9) | June 1, 7:00 AM | June 1, 12:00 PM |
| AEST (UTC+10) | June 1, 8:00 AM | June 1, 1:00 PM |
| NZST (UTC+12) | June 1, 10:00 AM | June 1, 3:00 PM |
The five-hour figure is the standard estimate. Maintenance can wrap a little early if the deployment goes cleanly, and it can run past the listed end time if HoYoverse hits a technical snag during rollout. While servers are closed, you cannot log in at all.
Stellar Jade compensation for the 4.3 downtime
You are paid for the wait. Once the update goes live, the compensation lands directly in your in-game mailbox, so there is nothing to redeem or activate.
If your account had not reached Trailblaze Level 4 before servers went offline, you are not eligible for this version's reward. To collect, open the game after servers return, head to your mailbox, and claim the message before the version ends. Seeing the Jades added to your balance confirms it worked.
What to do before the servers go down
If you are reading ahead of a future patch's maintenance, the prep is the same each time. Clear anything that resets so you do not lose value during the downtime.
- Spend your Trailblaze Power so it is not sitting unused.
- Finish any expiring events from the previous version before they close.
- Complete your daily missions to avoid losing that day's progress.
- Pre-download the update once it is available, so you can jump in the moment servers reopen.
- Plan your pulls and check your inventory for the new banners.
The 4.3 pre-install was sized at 3 GB on PC and 2.1 GB on Android and iOS.
What launched with Honkai Star Rail 4.3
Version 4.3 is titled "The Lethe Below the Living" and pushes the Planarcadia storyline forward in the game's second year of service. The headline addition is Mortenax Blade, with Yao Guang, Cyrene, and Phainon also featured across the 4.3 banners.
With maintenance complete and servers back online at 11:00 AM CST on June 1, 2026, the simplest way to confirm everything is ready is to launch the client, install the patch, and check your mailbox for the Stellar Jade compensation.
