-    An increasing number of censoring countries are using Deep Packet
-    Inspection (DPI) to classify Internet traffic flows by protocol.
-    While Tor uses <a href="<page docs/bridges>">bridge relays</a> to
-    get around a censor that blocks by IP address, the censor can use
-    DPI to recognize and filter Tor traffic flows even when they connect
-    to unexpected IP addresses.
