Following the rapid growth on the Merula network we have been planning a major upgrade to our core switching platform to Juniper devices.  These will allow us to dramatically increase the capacity between sites and add further stability to our network.  Over the coming week, work will take place to introduce them into our network.
This will in due course lead to some limited downtime as links are migrated. We will update here with specific slots for this but wanted to provide some initial details for this work.
Any initial questions, please email support via the normal means.
