We'll be performing overnight software upgrades on our BGP routers. Starting Saturday 22nd March. Routing tables update before a restart so there should be minimal impact to traffic.
One of our L2TP routers will upgrade at 4:30AM Saturday 29th, This will cause a drop and reconnect (twice) of L2TP services.
This work has been completed. However, we expect to start another upgrade process shortly as there are some new features we'd like to start using that are in later software.
