I lost a blog server.
postmark.net were a free web-based email provider.
Their homepage tells a sobering tale:
Early last week, Postmark’s repositories of user mail and account information were lost to a serious hardware failure. The resulting damage left us unable to recover any useful data, and as such, Postmark.net is shutting down. In its stead, we recommend Google’s own Google Mail service, which offers superior storage and search capacities.
