Update:
The snowflake broker has now more than one IP address. The scripts have been modified to reflect that and add all snowflake IP addresses to the allow list.
If you are using the scripts, you can use the appropriate update*.sh to fix that. If you are running a cron with the refresh-authorities.sh on a daily basis, you should replace that with the new file. You can also run it manually and your allow-list will be updated.
Background:
A set of bash scripts used to apply iptables rules to fight the current
DDoS attacks. They require no dependencies to install except
iptable/nftables which all Linux flavors already have and require no
particular expertise. The issue was discussed here:
