Statement from Voxility:
We have encountered a rare software issue on one of our network aggregators.
We are working with our vendor to find a permanent fix.
For now the only solution is a hardware reset that will affect the customers directly connected to this equipment, or routed through it.
Affected equipment: FRA-EQ5-01C (this can be noticed in trace).
Start time 07.04.2018 - 02:00 UTC.
Estimated downtime: ~10 minutes
Update: Due to re-routing our network was not affected by this maintenance.
