The DNS servers Verizon has assigned to my account (71.252.0.12 and 68.237.161.12) aren't able to resolve the domain name choralis.org. I've tried several other DNS servers from different networks, and they all have the entries for that name, which has been in DNS for years without interruption (and in fact, Verizon's own DNS servers were able to resolve the name until last night). What's the process for getting Verizon to refresh their DNS databases?
