Marathon Servers Down for Update 1.0.0.4: Full Maintenance Trend Summary

TL;DR

• Marathon servers are temporarily offline for the deployment of Update 1.0.0.4.
• The maintenance began on the morning of March 11, 2026, affecting all platforms.
• Players are reporting a surge in 'Weasel' error codes during the transition.
• Bungie is actively investigating connectivity issues and background stability.

What Happened

On March 11, 2026, Bungie initiated a global maintenance window for Marathon, resulting in the servers being down for several hours. The developer deactivated login capabilities to push Patch 1.0.0.4, a mandatory update designed to address lingering launch-week bugs and performance bottlenecks. During this period, users were automatically disconnected from active sessions to prevent data loss or progress discrepancies. This downtime was scheduled to coincide with standard weekly reset windows to minimize long-term disruption to the player base.

Key Developments

Bungie confirmed they are specifically tracking an influx of 'Weasel' error codes, which typically indicate a disconnect from the game servers or a failure to authenticate with the platform's network. In addition to the Weasel errors, players have documented instances of 'Marionberry' and 'Centipede' codes appearing as the maintenance commenced. The development team released Patch Notes for 1.0.0.4, which highlight fixes for weapon balancing and UI glitches that had been reported since the last minor hotfix. To ensure a smooth transition, players are encouraged to view the official Marathon Patch Notes for a complete list of technical changes.

Bungie is currently investigating reports of players receiving Weasel error codes as we prepare for the 1.0.0.4 rollout.

Why This Matters

The success of this maintenance window is critical for the game's competitive integrity and seasonal progression. Because Marathon is a high-stakes extraction shooter, server instability can lead to the loss of rare in-game gear and character progress. Ensuring that Update 1.0.0.4 is properly integrated helps stabilize the economy and prepares the game for upcoming limited-time events. Furthermore, resolving the 'Weasel' errors is essential for maintaining the active player count, as frequent disconnects directly impact the matchmaking pools and queue times for all active participants.

What Happens Next

Bungie expects to restore server access once the database migration and patch deployment are finalized later today. Once the maintenance is complete, all players will be required to download a client-side update of approximately 2.5 GB before they can log back into the game. Players should monitor the official Bungie Help social media channels for the 'All Clear' notification before attempting to re-enter high-stakes matches. No further extended downtime is currently scheduled for the remainder of the week.
