Basically the email says a lot of nothing. ”There are no Dreamhost hacks nor Wordpress hacks.” Yet in the screenshot of twitter below people who run Wordpress CMS and are hosted by Dreamhost seem to be having some issues. Do your own search of twitter (search.twitter.com) and see if it is still going on.
While it may be true that it was not technically a Dreamhost hack. Help us out and find the root cause. Tell us what the root cause was/ is. And leave steps to stop it or kill it. Sending people an email saying how it was not your fault is generic and a huge waste of time. Having read the email I don’t know anymore than I did before reading it, nor have I even narrowed anything down.
Companies spend so much time on PR spin, advertising, marketing, and playing defense it is ridiculous. Just make a good product and if and when there is an issue, just come up with a solution. In the solution you can point out how it wasn’t your fault and I will totally believe you. I will even think you are the most awesome company for going above and beyond. But wasting my time only to point out how it isn’t your fault gets us nowhere, except more annoyed with you.
