Quoting Kim Oldfield (luv@oldfield.wattle.id.au):
They are using 2 DNS names (which happen to translate into 2 IP addresses). Do you know what technology (load balancers, anycast, etc) they are (not) using so you can substantiate your claim that are violating the RFC?
No, for all I know, they're both massively redundant anycast network clusters spread all over multiple geographic areas, networks, and power grid segments, the way many of the 13 root nameservers are.
Of course, this _does_ happen to be Bluehost, Inc., which has a long history as a singularly technically deficient and inept firm, particularly since being acquired and massively downsized. In light of which, I will sleep soundly in the face of doubts about my being unfair. ;->
Also FWIW I've setup monitoring scripts to check all zones that I'm remotely involved with for being resolvable via 8.8.8.8. I configured such scripts to not alert me unless it's down for more than 5 minutes, because 8.8.8.8 falsely saying that an entry doesn't exist is something that happens periodically. It's something you probably won't notice when using the Internet, but if you have a script that checks dozens of zones 24*7 then it's going to happen. I suspect that there's something a bit broken in Google DNS, but I've had bigger problems to fix. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
