We became aware of many IO Phone numbers not working for incoming calls and giving a busy signal around 12:41pm on 4/28/2025. We found that a significant amount of phone numbers were disconnected at 7:11am on the same day. Working with our carrier, we were able to determine the issue and reconnect the numbers around 2:45pm. We do not believe it was an attack or hack of our services. Instead it appears to be an accident from a dev server. We have already made changes to prevent a recurrence and are looking into other measures to prevent similar issues in the future. If you were one of the affected users, we sincerely apologize for the inconvenience. As a precaution we updated the connection credentials so you may have had a few minutes around 3:10pm that you received errors.
The IO Phone service has become a very widely used service, and we aim to keep it functioning at the highest level. We have recently added many new features to further improve the service such as phone recording and allowing attachments to be sent via MMS from the browser. You can read more about those features and our latest updates here. Thank you.
