Rebuilding a new mysite host


Had a situation the other day where MySites went down - users were only getting 404s.

IE - unchecked show friendly http messages and this was the error:

HTTP/1.1 200 OK Server: Microsoft-IIS/7.5 Error -

I then discovered that the MySite host site collection was missing - no longer listed in view all site collections where it should have been listed as mysite.domain.com/

Googling has revealed to me that you get this error message when the root site collection is missing from the Web App

First step: detached and reattached the mysite content db from the farm - required to clear any entries in the Config DB

Second step: recreated the MySite on the root

And all is well again

The reason the MySite host got deleted was because I setup auto site deletion policy on the MySite web app - all good governance but the problem was that the MySite host site collection site admins were a couple of service accounts with no email addresses - hence instead of 28 days of warning emails - BAM! - the site just got vapourized

Lesson - make sure you can access your MySite host
