US Central is down due to a SYN Flood attack. I will keep you posted.

Because of repeated DDOS attacks targeted towards the US node, I have no other option than to migrate the node to another hosting provider that offers DDOS protection, as the current provider does not. This means the current US node will remain offline and that the IP address (both IPv4 and IPv6) will change as a result of this migration.
I plan on having the new node up and running within 24 hours. I apologize for any inconvenience this prolonged downtime may cause.

As promised, a new US node has been setup. For more information, please refer to the news post linked above.
I apologize for any inconvenience this may have caused. Thank you.

US East is under a DDOS Attack from an IP originating from Turkmenistan.

To mitigate the attack, I've temporarily disabled DNS over HTTPS (DoH) on the US-East node, since the /dns-query endpoint was being targeted.

The attack seems to have ended. DoH has been re-enabled on the US-East node.
