Is Synthflow AI Down?

Maintenance has started --- [2026-10-28T15:03:07Z] (maintenance_scheduled) Dear Customer We’re carrying out planned maintenance on our telephony network to improve its reliability. The work affects customers on our Global + US region and takes one hour. Some calls may be interrupted for up to five minutes during this window. How you connect to us determines whether you’re affected: • **You use SRV records:** you aren’t affected. Your calls move automatically to an available server before we restart each one. There should be no disruption to your traffic. • **You connect through a hostname without SRV records (A records):** your calls may still be sent to a server while we restart it, so some calls may be interrupted. • **You send calls to a single Synthflow IP address:** calls to that address may be interrupted for up to five minutes. • **You connect to more than one Synthflow IP address:** we update the servers one at a time, so calls can use the others while each one restarts. There should be no disruption to your traffic. To avoid any interruption, we recommend using SRV records. If the work runs longer or the schedule changes, we’ll update this page. We’ll also post when the work starts and when it’s complete. If you have any questions or are still seeing issues, please contact Synthflow Support at [https://support.synthflow.ai/ ](https://support.synthflow.ai)

**Summary** From Tuesday 27th October, some customers who use sub-accounts couldn’t see some or all of their sub-account workspaces in the dashboard. Access has been restored for every affected workspace. **Impact** Affected users couldn’t see or open some of their sub-account workspaces from their main workspace. Calls and voice agents kept running as normal. **Data impact** No data was lost. The sub-account workspaces and everything in them stayed intact. Only the link that lets the main workspace see them was affected. We contacted each affected customer directly. **Root cause** This was caused by the same issue with one of our third-party providers behind the Settings and SSO login incident on 27–28 October. That issue cleared the information that links some sub-account workspaces to their main workspace. Without that link, the sub-accounts stopped showing in the dashboard. We found this while checking for any further effects of the earlier incident. **What we’re doing to prevent this** • The safeguards we added on 28 October now also stop the link between a main workspace and its sub-accounts from being cleared if a third-party provider fails. • We’re moving off this provider so this can’t happen again. --- [2026-10-28T10:49:22Z] (resolved) **Summary** From 17:15 UTC on 27 October to 08:42 UTC on 28 October, some customers in our US and EU regions could not open the Settings page, and some could not log in with SSO. Both problems are now fixed and have not come back. **Impact** Affected users saw the Settings page fail to load, and some SSO logins failed. Calls and voice agents kept running as normal. **Data impact** A small number of workspaces may have lost some workspace-level settings, such as the workspace name. No customer data was lost. We will contact each affected workspace directly to help restore these settings. **Root cause** An issue with one of our third-party providers caused some workspace settings, including the workspace’s region, to be cleared. Without these settings, the Settings page and SSO login stopped working for affected workspaces. Our first fix restored the settings, but they were cleared again until we found and fixed the underlying cause. **Timeline (UTC)** • **27 Oct, 17:15:** We started investigating reports of Settings and SSO login failures. • **27 Oct, 18:33:** We restored settings for the affected workspaces. • **27 Oct, 21:11:** Some settings were being cleared again. We found the cause and began restoring all affected workspaces. • **28 Oct, 08:42:** We finished restoring every affected workspace and added safeguards. Our checks found no affected workspaces after this. **What we’re doing to prevent this** • We’ve added safeguards that stop workspace settings from being cleared if a third-party provider fails. • To migrate off this provider to prevent this issue from happening again in the future We’re sorry for the disruption. If you still see problems with Settings or SSO login, please contact support at support@synthflow.ai, or reach out to your account representative.
