Hi, Last week the call-cc.org was under heavy load due to the amount of parallel requests to relatively heavy services like gitweb and trac, causing all services provided by the call-cc.org server to respond very slowly.
Considering the amount of parallel requests, presumably they were being performed by automated software, which were ignoring robots.txt. Last Friday (2024-08-09) the situation became critical, with some services becoming totally unavailable for some periods of time due to exhaustion of system resources. As a reaction to that, many IP addresses that were abusing the services were blocked via firewall. That was done quite aggressively and it is possible that some innocent IPs got blocked -- if you know of such cases, please contact me. Apologies for the inconvenience that this situation might have caused. All the best. Mario -- http://parenteses.org/mario
