inaccessible error messages on our domain

Dear readers

We had recently some 'Downtimes' and I want to appoligize for it.
It is unclear if its any new plugin in the DNS System or caused by any changes from Google Hosting.

The error Messages looks like that:

Google mentioned that the traffic is unually in leechermods.com

website: http://www.leechermods.com/

Please post a message here if you had the same errors by visiting the website.

We are sorry for the delay especially for our running contest.
The winners will be announced asap.
