Re: ClearCloud DNS
Effective September 1, 2011, GFI’s ClearCloud DNS service will be discontinued and no longer available for consumer use…
you will need to reconfigure your network connection [removing ClearCloud]. If this is not done prior to September 1, 2011, your Internet connectivity will be interrupted.
