Network Maintenance Upgrade
Completed
Ok, Phil has had to abort the upgrade at Sov House, the 100Gb LR4 Cables are too big for the rack so will need to plan on moving the Router down a few U's so the cables can fit and rack door remain shut.
This will require about 30min of downtime at Sov House to move the router etc.
A new maintenance window will be announced when we are ready to relocate the Router.
To to Recap. Upgrades at Volta are now fully completed. Sov House needs more time / planning etc of which date to be confirmed.

Update
Ok, the final upgrade at Volta is now complete. Phil is now heading over to Sov House DC as he cannot see light on the new Fibre's.
There is no impact to service at Sov at the moment as the original fibres remain up.

Scheduled
This Maintenance window will start at 10pm on 16th November.
The Down Links from our Juniper MX204 Routers at Volta and Sov House are both currently running at 20Gbps to our Juniper QFX Core Switches. We have already installed the new Fibres to increase this to 100Gbs to all core switches.
The previous maintenance upgraded all switches and site to site links to 100Gbps leaving Uplinks to MX204s remaining at 20Gbps to avoid the routers (with large buffers) microbursting the switches (with small buffers) and causing issues. So the upgrade to full 100Gb had to be done in stages.
This Maintenance window is to make live the new fibres and will be the final part of our new 100Gb Backbone Network.
This notification is to make you aware that this could cause a disruption to all services while the MX204 Routers reroute and learn the new paths to our core switching hardware.
The Maintenance window is set for 2 hours, however the actual disruption is likely to be only a few minutes per switch while the traffic reroutes to the new Fibre.
The change of config script will be built in advance so can be applied quicky to reduce the disruption.
