Core router software upgrade — YUL

计划安排

We will upgrade the operating system on the two core routers in YUL, one after the other. Each router is drained before it reloads, so traffic stays on the other one. Expect up to 60 seconds of reduced redundancy per router while its BGP sessions reconverge; no machine should lose connectivity. Out-of-band access is unaffected.
