We have been testing our routers extensively since our routers are installed (July 15, 2015) and now we will proceed in finalising the network upgrade.
On December 15, 2015 at 00:00 – 06:00 (CET), we will announce our routes on our own routers. First of all we will migrate each VLAN one by one by moving the gateway. Because of gratuitous ARP we expect no impact.
We will also migrate the BGP announcements from the current routers to our own. There might be a couple of seconds downtime and we expect that the reconvergence will take maximum 1 minute after which the new AS path is picked up by routers worldwide.
We expect at most a couple of minutes downtime per VLAN within the maintenance window. After this has been finished this will also allow us to detect and react to DDoS attacks faster which is of course great news but more on that later.
Should you have any questions regarding this maintenace then please don’t hesitate to get in touch with us via firstname.lastname@example.org.
All the best,
