Our team continues to monitor the recovery to ensure full stabilization across the remaining Tachyon devices. We will provide a final update once all devices have fully reconnected and the incident is resolved. --- [2026-09-01T14:14:23.178-07:00] (identified) We have identified the cause of the connectivity disruption affecting Tachyon devices. Our team is actively working on a fix to resolve the issue. We will continue to post updates as progress is made. No other Particle device type or SKU is affected by this incident. --- [2026-09-01T13:48:15.208-07:00] (investigating) Affected component: Tachyon device connectivity (SKUs: TACH4NA, TACH8NA, TACH8ROW) Started: Today, 1:22 PM PDT Description: We are currently investigating a connectivity disruption affecting Tachyon devices (SKUs TACH4NA, TACH8NA, TACH8ROW). The Particle team is actively investigating the issue and will post updates as more information becomes available. No other Particle device type or SKU is affected by this incident.

This incident has been resolved. All Tachyon devices have successfully reconnected and connectivity has been fully restored. No other Particle device type or SKU was affected by this incident. --- [2026-09-01T11:42:43.888-07:00] (monitoring) The majority of Tachyon devices have reconnected and are back online. We continue to monitor the recovery to ensure full stabilization across the remaining devices. We will provide a final update once all devices have fully reconnected and the incident is resolved. --- [2026-09-01T10:40:52.607-07:00] (investigating) Affected component: Tachyon device connectivity (SKUs: TACH4NA, TACH8NA, TACH8ROW) Type: Unplanned Incident Status: Investigating Started: Today, 10:30 AM PDT We are currently investigating a connectivity disruption affecting Tachyon devices (SKUs TACH4NA, TACH8NA, TACH8ROW). The issue began following a routine update to our connectivity infrastructure, which triggered an unexpectedly high volume of simultaneous device reconnection attempts. Our team is actively working to restore service and stabilize reconnections. We will post updates as we have more information. No other Particle device type or SKU is affected by this incident.

One of our cellular network partners will perform a scheduled network routing upgrade to improve the performance and long-term stability of cellular connectivity. Start: Tuesday, November 10, 2026, 12:00 AM PST (08:00 UTC) End (estimated): Tuesday, November 10, 2026, 8:00 AM PST (16:00 UTC) Scope: Only the following Particle SKUs may be affected. All other cellular devices and Wi-Fi devices are not affected. Boron: BRN404, BRN314 B-Series SoM: B404, B504, B524 E-Series: E404, E314 Electron: ELC404, ELC314 M-SoM: M404, M524 Muon: MUON404, MUON524 Tracker SoM: T404, T524 Tracker One: ONE404, ONE524 Monitor One: MON404, MON524 Impact: No major data service interruptions are expected. Some devices may briefly disconnect and reconnect while their routes move. Devices reconnect on their own, and no action is needed. We will post updates here as the maintenance progresses. If you see connectivity problems after the maintenance window, please contact Particle Support.
