Amilcar down? Can't reach some sites

Description

Dear MF/PL team!

something is broken with my connection to Amilcar. I presume it is some security settings to avoid DDOS? The two sites that we have on that webserver are both unreachable for me as is https://amilcar.mayfirst.org/ but they were fine just 10 minutes ago. I can ping the server fine but if I try open it in my laptop's browser or my phone's browser I get an "unable to connect" as long as the phone is also connected to the Wifi - if I go on mobile internet I can connect.

Can you give me a hint on how to avoid this in the future and how long it will take for the IP to be unblocked?

Thanks, David

Hi David,

If you've inadvertently triggered our intrusion detection system our fail2ban software will modify the firewall to block your ip number for about 5 minutes before unblocking again. If whatever pattern that triggered the block continues it can result in a longer block. What ip number do you see when logging into https://ip.mayfirst.org from the machine that appears to be blocked?

I can use that number to check the logs and determine what is happening.

Thanks JaimeV! It didn't persist and I had changed IP the next day already anyways because I was traveling. Anyhow, good to have the information you provided in case I manage again to trigger the intrusion system ;) Best regards, David
