I run about 5 different hosted servers, through a variety of hosting providers. In the past two months, one of the servers I work on has been down twice. Both times were unexpected and fairly long (36 hours and 4 hours). The server in question is a VPS not a shared server. Given my experience with my other servers/providers (both VPS...

Is there a preferred method of gracefully upgrading a web site? I have a completely new code base ready to go on a site, but updating it will take several hours.

Unfortunately my current company doesn't have a "research project" policy so I can't put too much effort on a side project (or I may never finish it).

What correlation is there between datastore and task queue downtime? (I'd like to use the task queue to defer some operations in the case of datastore downtime.) ...
The app engine datastore, of course, has downtime. However, I'd like to have a "fail-safe" put which is more robust in the face of datastore errors (see motivation below). It seems like the task queue is an obvious place to defer writes when the datastore is unavailable. I don't know of any other solutions though (other than shipping ...
