Well to be completely fair to DNSMadeEasy, this failure wasn't necessarily their entire service, it was just the one nameserver pingdom was testing, ns10.dnsmadeeasy.com. However, both GoDaddy and Dynect were tested using just one nameserver, so the comparison is fair. I'm not sure what the cause of it was though.
