On 5/12/2016, my blog was transferred from wordpress.com , to a recently bought domain: http://amaitos.eu. The new domain is hosted at interserver.net! The people at Interserver seem to be doing a really good job. It simply took 10-15 minutes to transfer all of my staff from wordpress.com to the brand new wordpress installation at interserver :)). And using a simple .xml file for import/export did the trick!
A solid reason to recommend them!
