Recently the maintainers of the big Greek news site Parapolitika, the guys from the Greek subsidiary of Tatchit contacted us asking for our help: the site was going down routinely for some reason after going live (it was rewritten on Orchard from the legacy engine). The Orchard application was sometimes using up all of the server's CPU (despite it being a 24-core beast) and crashing the IIS worker process in the end. This needed some urgent fix because websites tend to be only worthy if they're alive...
On Friday we completed a short but important emergency assignment: getting the GI Joe Search & Rescue team's website back online. The website was moved to a new hosting company but wasn't feeling all right (the standard IIS 404 page greeted the visitors). This was especially problematic given that the team needed the website for their communication on the weekend.
That's when we got contacted on behalf of the team and started investigating. After checking the logs and verifying the integrity of the deployment we recognized the source of the error: although the site's database was seemingly restored all the tables were empty! Running the restore again fixed the database and thus solved the issue altogether.
Naturally we didn't charge the team for this emergency fix: they don't charge you when you need their help either!
