Heartbleed and Hostgator customers
You know why I always recommend hostgator and it because of situations like this.
they are proactive in securing their servers, and because they update, they were not effected as severely as other hosting companies.
they have a tester here
it is only for hostgator hosted sites
also, as for 911websiterepair and madeforjoomla. we were never effected because we keep our server up to date and the newest versions of openSSL are not vulnerable. Of course, that keeps our sites in the same constant upgrade cycle as yours, but it sure has paid off to do it.
Let us know if you have any questions
