Analysis: Number of hops: 19
Last hop responding to ICMP: 15, UDP: 15, TCP: 0.
There appears to be a firewall at (hop 16) that blocks ICMP (ping) packets.
There appears to be a firewall at (hop 16) that blocks unwanted UDP packets.
There appears to be a firewall at 22.214.171.124 (hop 1) that blocks unwanted TCP packets.

T1/T2/T3 are the round-trip times in milliseconds (1/1000ths of a second).
T1 uses a proper ICMP-based tracert (Microsoft style). T2 uses a UDP-based traceroute (Unix-style). T3 uses a TCP-based traceroute (port 80).
Since many ISPs now block ICMP and/or packets to unknown ports, T3 (rarely used by traceroute programs) typically shows the best results.
Best times may be theoretical (if it takes 80ms to hop 10, and 50ms to hop 11, we say the best time for hop 10 is 50ms).
If no reverse DNS entry is given for an IP, we display 'unknown.example.com' if the domain name is known.
