Sounds like it might be a different issue than what we were investigating, but it's not unreasonable to think it may have had the same root cause. The outage impacted all UDP session devices, which would include all Gen 3 devices. But a full power cycle would have resolved anything that came as a result of this incident.
Glad to hear a network rebuild resolved it, but that obviously shouldn't have been necessary.
Please let us know if this issue occurs again, and we'd be happy to work through troubleshooting steps with you to understand if the root cause is related to the one cited above.
