Network Looking Glass
Check routes and latency to other points on the Internet from our networks.
Test File
The following files are on a 1000 Mbit/sec link and contain randomized binary data (to prevent compression) which should reasonably test throughput from our network to any remote destination.
- Chicago: testfile.chi.steadfast.net
- New York: testfile.nyc.steadfast.net
Test IPs
The following IPs are on our primary network and should be used for remote ping/traceroute tests. Note: Just using steadfast.net will not work. Our web site and customer support systems are hosted on a different ASN to provide redundant access in the event of a network outage. Systems located on the secondary ASN are not intended to match the performance our primary network provides.
