A few factors are at play here. Are all DC's in the same site? If not 
ensure Inter-Site Transports are configured properly.

By default the KCC(Knowledge Consistency Checker) should make 
modifications to the replication topology every 15 minutes. You will not 
see instant site links created when a DC goes offline.
