Earlier this evening we experienced some issues with an interlink between Telecity Reynolds House and Telecity Williams House in Manchester.
Starting 6:06pm, we started receiving spanning-tree topology errors via the link (provided by Geo) causing the link to flap. This continued randomly until approximately 8:15pm and has been stable since.
This segment of our network is a resilience link, ordinarily not in use so any issues should have been minimal as traffic does not normally traverse this link.
Once we receive more information from our supplier, we will update this post.
