Hola Luciano,
Esto es lo que comentó Cogent (operadores del root server C) y también publicó Paul Vixie (que es un colaborador/rootops de C-Root) en
https://c.root-servers.org
2024‑05‑23 - On May 21 at 15:30 UTC the c-root team at Cogent
Communications was informed that the root zone as served by c-root had
ceased to track changes from the root zone publication server after May
18. Analysis showed this to have been caused by an unrelated routing
policy change whose side effect was to silence the relevant monitoring
systems. No production DNS queries went unanswered by c-root as a result
of this outage, and the only impact was on root zone freshness. Root
zone freshness as served by c-root was fully restored on May 22 at 16:00
UTC.
Sin embargo, hay otra fuente (aún estoy buscando evidencia, por lo que no es 100% confiable hasta ahora) que menciona que Cogent dio la semana pasada como lease una subnet /17 a un tercero y sin querer, esa red contenía un /24 que sería el management network de C-Root.
La información aún fluye, pero no sé cuánto más se logrará saber por ahora
Saludos!
