Update - Signaling congestion has been eliminated and network performance has been restored to prior levels. We will continue to monitor as remaining devices reconnect.
Apr 23, 07:01 UTC

Verifying - We are seeing 2G and 3G sessions recovering. We will monitor the situation to confirm resolution.
Apr 23, 06:40 UTC

Update - We are seeing service mostly restored and working well for LTE devices. Our upstream carrier partners are still working to manage signaling traffic to bring the remaining 2G and 3G devices online.
Apr 23, 04:58 UTC

Update - Issue has been identified as signaling congestion from large number of devices reconnecting. Carriers are working to increase capacity on their systems
Apr 23, 03:26 UTC

Update - Devices are coming back online from the maintenance window, however this process is moving slower than expected. We are working with our carrier partners to speed this up.
Apr 23, 02:54 UTC

In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Apr 22, 22:55 UTC

Scheduled - One of our carrier partners will be performing planned network maintenance on core packet networking infrastructure on April 22nd, beginning at 22:55 UTC and running until 03:00 UTC April 23rd. This maintenance is necessary for improvements to preventative security measures as well as making overall improvements to network operation. Indigo SIMs will not be impacted.

Impacts: During the active work beginning at 01:00 UTC and through 01:30 UTC April 23rd there may be brief losses of data routing and packet deliverability, resulting in connections being dropped or destination hosts becoming temporarily unreachable. PDP contexts (packet-switched data sessions) and automatic IP address assignment requests may timeout. SIM operations (activation, deactivation, pausing, and unpausing) should not be affected. Tower authentication and circuit-switched SMS should not be affected. Dashboard and API will not be affected.

We recommend avoiding performing critical maintenance or operations on devices during this maintenance window. If you have any questions, please feel free to reach out to support@hologram.io, and the Hologram team will be standing by during the maintenance window to answer any questions.
