How to Appologize For Downtime
This my dear readers is how you issue an apology.
We are committed to making myBalsamiq known for its uptime, but clearly we have a long way to go. We are learning, and I feel very sorry that our early adopters have to pay for our inexperience. :(
They go on to offer an extremely generous credit for the downtime as well. However, to me that is secondary. All I think users really want to hear is that you are honestly sorry and that you will make your best effort to ensure it doesn’t happen again.
