Change Activity Details: We are completing a round of code upgrades on our Internet Border Routers. We will be working on three of these during this maintenance window. ibr01.hstntx2 ibr02.hstntx2 ibr02.hstntx1 Each router requires a reboot to load the new code. To ensure uninterrupted service we will reroute customer traffic around a router before we reboot it. However, we have seen from our previous code upgrades there is a possibility that rebooting/isolating one of these routers will causes another one of these particular routers to reboot unexpectedly. This behavior has been attributed to a bug that is corrected in the upgraded code.
Impact Statement: In the event that one of the 3 routers unexpectedly reboots; some customers may experience a brief period of packet loss and latency, to and from their server. This will be due to route convergence as traffic takes a different path while the router reboots, and then switches back to the original path after the router has come back online. This interval should be less then 5 minutes. However, most customers will not experience interruptions in service while we are performing this work.
