Host in Finland
Hosting in Finland is expensive compared to the global price level but the data protection and anti-espionage laws in Finland are top notch.
Price leader is https://shellit.org in Björneborg with data center built into a formed Finnish Defense Forces cave system inside the Finnish bedrock and the company uses exclusively renewable (mostly wind) electricity. Also if serving mostly Finnish customers the ecologicality of hosting in Finland will be appreciated by your customers. Shellit.org offers affiliates a one-time commission of 5% of the first bill of referred customers.
http://mediam.fi/ is the main company of http://kotisivut.com which I have been a customer of for since 2007-03-28 and have never ever had service outages that were not caused (and fixed a little later on) by me. Naturally I have needed to renegotiate the terms of our contract on numerous occasions because there is really no sense in paying list price for ICT IaaS or telephony. I am happy to find that they founded http://helsinkidc.fi/ their own fully owned and operated data center so I can rest assured they will be able to provide ample resources for decades to come.
Host in Lithuania
https://www.time4vps.eu/ is probably the global price leader as of Summer 2016. They have an affiliate program to which I subscribe to and also a reseller program. I am not yet their customer but 512MB for 0,66€ / month + VAT of your domicile with a biennial contract, how much longer can I resist?
Host in Netherlands
https://www.transip.eu/ has been my economical, reliable and friendly hosting guys since July 2013 and I can full-heartedly recommend them as a high quality and reasonably priced solution to serving Central Europe. Transip.eu is proud to host a Debian package repository mirror for super fast installations and upgrades.
Host in France
https://www.scaleway.com/ I am not a customer of theirs but their price is rather good and have been recommended them by someone I trust. Consider if you need to serve Central Europe.
