Looking Glass

SoftLayer Looking Glass is an interactive resource available to the public that can be used to test latency between SoftLayer data centers and between a router location and target address, subnet or hostname.  Looking Glass tests latency between a location and its target through a variety of methods, including ping and traceroute commands, and enables users to test network latency through a variety of test downloads based on size and data center location.  Users operate Looking Glass under the premise that only manual queries will be made.
