And would you be willing to pay $1 extra/domain for all of that? Lets face it, dynadot gives some of the best bulk discounts period and have probably the best interface in the industry which is why we all use them.
I pay that for my web hosting but not for my domains, if you need that kind of uptime for your domain registrar check out
www.pairnic.com.
I myself use dynadot, moniker (very little anymore), fabulous, and internet.bs.
to note I also have accounts at:
godaddy
enom
namecheap
reseller.biz
resellerclub
name.com /name.net /domainsite
opensrs
register.com
networksolutions
joker
domainit
pairnic
dotster
key-systems
gandi
directnic
domaindiscover
rebel
dynadns
easydns
I'm not worried...
