We are seeing some VLANs on our core network flap when they pass through a core switch in Telehouse West.
We may need to reset or reload this switch to clear this issue. This MAY cause some instability to the network for a short period and services hosted in Telehouse West may drop tor 15-20 minutes
We will update this as investigations continue
[update 1 – 23:30]
We have reloaded one of our core Juniper switches and are monitoring for stability.
[Update 24/12 9:44]
We have monitored the network after the switch reload at 11pm last night – and this has stayed stable with no further flaps. While the switch had no error logs during the incident it was randomly blocking traffic on some VLANs including a backup vlan between two core routers in Telehouse East and North. This was causing some packet loss / drops as the traffic was switching between links. We apologise for the issues seen however while we are aware this issue started during the day we needed to perform the reboot out of hours since it caused a 10-15 minute outage to services directly connected.
