Some users started mentioning they couldn't reach ClearCheckbook.com for a couple hours today. The server was running just fine and we weren't having any issues connecting to the site. Well, it appears GoDaddy (our domain registrar) was having some DNS issues today which was causing some people to have trouble accessing the site.
More information about the GoDaddy DNS issues can be found here: http://mashable.com/2012/09/10/godaddy-down/
We're sorry for any inconvenience this may have caused.
