As part of our rollout into Amazon's eu-west-1 datacenter, we enabled our terrific .Net hosting partner AppHarbor to provision MongoLab databases in Europe as well. If your AppHarbor application is hosted in Europe as shown above, any MongoLab databases provisioned through AppHarbor are automatically hosted there as well. See here for more instructions on how to enable the MongoLab Add-On. Pricing starts at Free for 240MB.
