Earlier today I restricted public access to one of my databases to the IP address of my VPN provider. I was then able to access the database over the VPN. However, after removing the IP address from the Access Control section, I am unable to access the db with the VPN off. When I add the IP back, I can access it again over the VPN.
It seems that the ACL is cached; the delete operation is not removing it immediately. Can someone confirm this behavior in Render? This non-deterministic behavior makes me a little nervous
