On September 17, the protocol of the US dollar-secured “stable coin” Tether (USDT) Omni Layer faced technical difficulties. Due to problems with the parsing engine that transmits Omniexplorer and Omniwallet data, Tether tokens have been frozen for several hours.
The Omni Layer team stated that the backend of the client used by the parsing engine stopped responding.
We have identified the issue with a backend client used by our parsing engine that appears to have locked up/become non responsive. We have restarted all applicable processes and are monitoring them while they verify & resync. This process should take ~ 2-3 hours to complete.

However, instead of the originally scheduled time, the process of checking and re-synchronizing the data took about eight hours. At this time, users of Tether and other services on the Omni protocol were advised to wait for a signal about the normal operation of all processes.
