With the recent rash of SqueakSource/GemSource server downtime, I've
bitten the bullet and updated the bootstrap process for Metacello to
automatically switch to a secondary repository if the primary repository
is not available.
I also recommend that if you are maintaining a Metacello configuration
that you update the class-side #ensureMetacello method for your
configuration to use the primary and secondary repositories for loading
the ConfigurationOfMetacello. A new version of the #ensureMetacello
method can be found here (I've also updated the config template):

Metacello project then you should take a look at this post:
