Bambu MQTT Incident Recurred July 20; Service Recovered by 18:30 UTC
Bambu's July 20 MQTT incident briefly prevented some users from starting prints, recurred after an initial resolution, and recovered after a rollback and server replacement.
Bambu reported an MQTT service incident that began July 20, was marked resolved, then recurred. Its status log says recovery followed a configuration rollback and replacement of a server with network-connectivity problems by 18:30 UTC. All systems were operational at this check; a detailed post-mortem remained pending.

Bambu's MQTT print-start incident recurred before service recovered at 18:30 UTC
Bambu's incident log says some users were unable to start print jobs through its MQTT service on July 20. The issue recurred after an earlier resolution. Bambu then reported a related configuration rollback, gradual recovery from 18:05 UTC, and replacement of a server with network-connectivity problems. At 18:30 UTC, the company said print initiation was operating normally. Bambu marked the incident fully resolved on July 21 and promised a detailed post-mortem. The current status page showed all systems operational at this check.
The useful boundary is narrow: Bambu's incident page confirms trouble starting print jobs and lists cloud printing as affected, but it does not establish impacts to remote control or live view, or prove that LAN printing was unaffected. Owners should use the incident log for the confirmed timeline and wait for the promised post-mortem before treating any recovery action as the final root cause.
Incident chronology and remaining gap
Bambu's status log records a recurring MQTT-service problem that prevented some users from starting print jobs. After the recurrence, Bambu said it identified the issue, rolled back a related configuration, observed gradual recovery, and replaced a server with network-connectivity problems. Those are reported recovery actions; the promised post-mortem is still needed for a complete root-cause account.
Owner read: The page was fully resolved and all systems were operational at this check. The status record does not support expanding the incident into claims about every remote feature or a specific printer model.
- What will Bambu's detailed post-mortem identify as the root cause and long-term corrective action?
What to do now: Use Bambu's current status page for live service health and wait for the promised post-mortem before drawing broader reliability conclusions
What is confirmed: Print initiation had recovered by 18:30 UTC and all systems were operational at the July 24 check
