A common misconception.  Hosts (including the host functionality
internal to a router) may deal with pings differently depending on load
-- for example, pinging a router might result in delayed responses if
the router is busy.  But routers do not stop forwarding pings when they
are overloaded.  In the absence of traffic filters, a router (in the
general case -- there's probably an exception to prove the rule) will
forward a ping (that is not addressed to the router) with the same
priority as it will forward a TCP frame (that is not addressed to the
router.)
