1 router? In THEORY, 24 hours (but see below). 5 routers? Not sure. The unoptimized route due to the loss of optimal routing 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 Taiwan got hit by an earthquake, it took almost one month after the router got recommissioned before things return to normal.
