We're getting bitten by this in the Netherlands as well. Two domain registrars, PCExtreme and Neostrada, merged with Versio, and Versio is now owned by TWS.
My company has domains registered with Versio (and PCExtreme and Neostrada), but the control panel was showing multiple domains wrongly flagged as 'processing', and actually getting through to customer service takes the better part of day by now. I'm not looking forward to our domains getting migrated due to these mergers.
Start looking for alternative registrars if your domains are hosted by Versio, Neostrada, or PCExtreme! The competent staff of PCExtreme and Neostrada seem to have evaporated in these mergers.
I'm using Infomaniak. I especially like their renewal warranty [0]. It's a few bucks more a year but they renew the Domain even if you are not paying and try to contact you by phone, snail mail etc. They also support IPv6 and DNSSEC.
I used to be on Versio, but moved to TransIP after the acquisition of Versio by TWS.
TransIP is not exactly the cheapest, but they work fine. Vimexx (which is under the same company as TransIP) is cheaper (closer to pre-TWS Versio pricing), but I'm a bit hesitant to trust a 'budget' registrar again.
Not sure if it meets the European criteria but I use a combination of DNSimple and Porkbun and am very happy with them both.
For less common ccTLDs, Gandi is still hard to beat since they support virtually everything. Apart from that, I have no regrets moving... I saw the writing on the wall about 2 years ago and moved virtually all my domains away from them.
Shame because they're good registrars. I wonder why the European requirement though (since the TLDs themselves are ultimately governed by the registries and you can always use your own - or third party, EU based - name servers).
I wanted to purchase a VPS and they took my money before asking for ID. I refused to give them an ID that I didn't have (because I don't have one) and they kept my money and refused to provide service.
So at least don't get a VPS unless you're ready to give ID, heh.
