Core router software upgrade — ZRH

예정된 작업

We will upgrade the operating system on the two core routers in ZRH, 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.
