Please be aware that on December 5th, 2019 00:01 to 06:00 our data center provider will be performing core router maintenance to install additional line cards. This is a low-risk maintenance window and we do not anticipate any disruption in-network or TCP connections. This maintenance is being performed on their core routers which serve DIA to us. In the event of a disruption, service would still continue over the other core routers/carriers. They will only perform the installation on a single router at a time and no reboots are required. We anticipate the maintenance window to complete in under 2 hours.
