We will close the post on Twilio’s Status Page. If you have been impacted by this incident and wish to continue to receive updates, please open a ticket with customer support.
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 will provide another update in 2 hours or as soon as more information becomes available.
