I can't remember if I cried
When my `-f root` hit an ACL line
But something touched me deep inside…

The day the telnet died

On January 14, 2026, global telnet traffic observed by the GreyNoise Global Observation Grid fell off a cliff. A 59% sustained reduction, eighteen ASNs going completely silent, five countries vanishing (telnet-wise) from our data entirely. Six days later, CVE-2026-24061 dropped. Coincidence is one explanation.
