it does respond to pings, your dns is resolving it to the wrong ip which is dead

This is the way. Looks like my DHCP server was handing out IPV6 addresses and DNS servers, which the clients were then using as authoritative for their lookups. No idea why. Never really seen that happen before. Disabled the IPV6 DHCP server and then made sure my IPV4 DHCP server was handing out the right addresses to clients and it started working again.
