        Monitoring

        We have observed that the recent impact was limited to devices connected over AT&T. Currently, we are monitoring the situation as approximately 3% of devices may still experience connectivity issues. These devices might encounter a poor data connection or have short-lived sessions.
        Our engineering team is actively working alongside the affected network provider to resolve the issue as quickly as possible. In the meantime, we kindly suggest that customers reset the connectivity through the console if they notice that some of their SIM cards are still experiencing issues. This can often help re-establish a stable connection for the affected devices. We expect to provide another update in 2 hours or as soon as more information becomes available.

Devices that attempted to reconnect immediately after losing connectivity should have been able to successfully reconnect to the redundant instances while the impacted one recovered. We will continue to monitor and will provide another update in 1 hour or as soon as more information becomes available.
