That doesn't really answer the issue, or the question. How are we supposed to get in touch when things go wrong? The blog post clearly showed that support was an afterthought and not properly QA'd.
Post to one of the product-related Google Groups like google-appengine@ or gce-discussion@googlegroups.com. We have support staff monitoring those lists seven days a week.
