Here in Brazil we had a similar issue... The cause here was the lack of maintenance contract between the Firewall Suppliers and the Government Department.
GeoIPBased Firewall Rule was deployed on the Public Health System in Brazil, saying: "To those servers, if IP is not from Brazil, drop!" After the service contract with the firewall vendor expired and was not renewed, automatic updates from Gei-IP-Base were blocked. The range 45.x.x.x was not allocated initially to BR, but in decurrency of phase 3 of IPv4 exhaustion on LACNIC, several blocks inside 45/8 were alocated to Brazilian ASNs. And that firewall did not receive the updates that would tell "hey firewall... those IPs are Brazilian now". And because of that, a significant part of the Bazilian Internet community had problems to access one of Public Health application on the Internet. That is described here at the following link (pt_BR) https://eng.registro.br/pipermail/gter/2019-September/077235.html After a MASSIVE campaign started on that mail list, and several colleagues sending repetitive e-mails to the responsible organizations, marking guys on facebook and linkedin... One day a magic was done and that blocks stopped.
