We have identified an issue with one of our core network switches, DS-129, located in LDeX 2 Manchester.
This switch has hit a known Cisco IOS-XE bug and requires a reboot to activate an IOS-XE update.
As this issue is currently service affecting, we will perform an emergency upgrade/reload of this core switch at 8:15pm this evening (UK local time).
Any customers directly connected to DS-129 core switch, or DS-108 leaf switch will see an outage of approximately 15 minutes. Directly connected customers have been notified directly.
Customers with virtual machines located on our Manchester cluster will also see some disruption during this time.
Other services should not be affected.
The upgrade and reload of this switch went ahead as planned and service was restored to affected devices at approx 8:32pm.
