1 router? In THEORY, 24 hours (but see below).

5 routers? Not sure. The unoptimized route due to the loss of optimal ro= uting info will severely impact everything. Maybe two or three weeks. Maybe= more than one month.

Heck, when a major Internet hub (i.e., one of the backbone routers) in T= aiwan got hit by an earthquake, it took almost one month after the router g= ot recommissioned before things return to normal.
