Hosted Grafana has more IPs that AWS security group will allow

A few days ago our hosted grafana connection to a RDS DB stopped working, turns our your IP list changed.

When creating ingress IP/CIDR rules for an AWS ec2 security group, the max number of rules you can have is 60.

https://grafana.com/api/hosted-grafana/source-ips.txt currently has 62 IPs.

Does Grafana hosted have CIDR blocks it can publish?

Update: ended up just adding a 2nd security group to my RDS. Not ideal.
