Global IP Transit, MPLS/VPLS/L2VPN
CustodianDC are scheduling in works to migrate all Maidstone DF1 and DF3 customers from our older edge platform to our newer edge platform.
This not only brings customers on to newer hardware, but it also brings them away from ageing patch panel infrastructure.
It is important in this instance to note that customers may experience interface flaps while works are being performed even if they are not being moved in that moment. This is due to the level of intrusive works required to move customer connections.
As a result please consider services to be at risk within these windows.
It is also important to note that customers being moved over to this platform will no longer be part of our own STP instance and so customers will need to handle loop protection on their own infrastructure.
Loops spotted on our network will have one port shut down to resolve the immediate loop potential and then those customers will be notified of the action at the end of the maintenance window.
Customers that have BGP instances with us which are already on our core platform but receive L2 through our older edge will have one instance shut and moved to cleanly migrate them away and reduce impact.
Customers that have BGP instances with us which are on our edge platform will have all sessions admin shut and then moved and re-established.
Standard Flat and static route IPT services will but shut down unconfigured and then reconfigured on to the new platform.
Backhaul services, protected or un-protected will be moved one at a time but will be affected in this window.
In all cases our team will ensure that services look to have returned after migration before moving on to the next service.
We will be moving customers one at a time within the window unless we have pre-agreed a time slot with you.
For customers with a single feed we anticipate affected services will not have connectivity for 15 minutes and no more than 30 minutes unless we are required to roll back the service or perform troubleshooting.
For customers with dual feed we anticipate affected services will not have connectivity for up to 30 minutes unless we are required to roll back the service or perform troubleshooting.
Affected customers will require their cables to be shortened within our own infrastructure and so this will be done within the move, due to this you may see more than one interface flap as we will endeavour to bring services back up before disconnecting a single link one at a time to perform those L1 alterations.
There are a large number of customer ports to migrate to the new platform so customers not affected in the first window should anticipate being affected in the second as we run sequentially though our infrastructure.
For any remaining customers we will schedule a third window now, however anticipate that we will be able to cancel it at the end of the second window.
For any questions or concerns regarding this maintenance please contact the NOC.
