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. 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.
