Read through the whole communication and have to say the Deutsche Telekom really failed to communicate clearly here. Most people who have ever worked in IT will fuck up some cert during some point in their career — but you have to not do that when you are expecting to earn that level of trust. And when you do fuck up, it really matters how decidedly and clearly you deal with that.

So first they don't produce any explaination, then they are on summer vacation? Truly WTF? If anything Deutsche Telekom has demonstrated that they are not deserving of the trust given.
