Terrace Networks Disputes Reports of Telnet Traffic Decline, Cites Measurement Errors

Summary

Terrace Networks challenges recent reports claiming Telnet traffic dropped significantly after a CVE announcement, arguing the findings contain critical errors. The company analyzed internal and open data and found no evidence that core network providers blocked Telnet, contrary to previous claims. They observed continued non-spoofable Telnet traffic from networks where others reported 100% drop-off, suggesting initial results may have been measurement artifacts or specific to certain conditions.
