So FR should move from its own servers to those of a major internet company?? Not so fast. All of a sudden FR's continued existence could be threatened by a corrupt government pressuring that company with all sorts of threats (investigation, IRS, etc.) if it continued to allow FR stories and comments disparaging that government/administration to be published from its servers. How long do you think FR would be able to provide a conservative voice on the net with the threat of being shutout??
I'm sure Jim and John would say "No thanks" to your suggestion.
MittRomney.com's A record currently resolves to 107.21.98.213, as Arin points out is owned by AMAZON-EC2-8.
And, by the way, SarahPAC.com is hosted by Rackspace, probably the biggest competitor to Amazon AWS. But that proves that Sarah doesn't see this as an issue either.
