I'm using their root servers (8GB DDR4 RAM) and never had any problems. The performance is just plain awesome and that one time I had a problem regarding the GDPR the support answered very fast and friendly.
To clarify, you d... Vairāk o need to have some knowledge on how to set up a server, but who is renting a server without that kind of knowledge anyways?
I never had any billing problems either. Of course you have to check the contract, but for VPS e.g. there is no minimum rental time, you can cancel the server after 10hrs of usage without any problem for example and only pay for those 10 hours. Mazāk

Hello Guys,
I can list of many reasons to stay away from this company.
1) Totally illegal financially:
Due to their illegal activity in financing procedure, I had to contact sub-department of "German Federal Ministry of Finan... Vairāk ce" ( abbreviated as BMF ). They charge VAT to non-EU members but after your payment, they do not indicate VAT in submitted invoice. Do not feed this gangstas with your money.
2) There is no way to cancel your service:
I signed up to their website and checked out a dedicated server with one month subs. I did not choose annual subscription, that's why monthly price was a bit higher. Before the end of three months period, I informed them that I did not need this service and thanked them.
What happened next?
They asked extra money in addition to given price in their website. In case you do not agree with their price, they threaten you by forwarding your documents to finance companies which has no sense for me. If they wish, they are welcome to Algeria.
They can't answer me when I ask why I should pay for a service which I had not bought.
3) Far away from basic technologies:
Imagine a hosting company which has been pronounced as "the best by some other commentors" has no credit card payment gateway
4) Configuration of your service is an illusion:
I have been over 15years in the market and I am able to manage some performance tests after buying a vps or a dedié and I did the same process after check out the shopping cart in Netcup's page. The weird thing is that what they promise and what you get are not the same. When you check out the memory of dedié, it shows 64GB ram in command prompt but if you wish to check the real ram performance, it was not going above 40% of guaranteed ram in a virgin server.
Dedicated traffic premised by Netcup was 1gbps but it was around 300Mbps during the test. Seems like dedicated server is not a real dedicated server and we had noisy neighbors.
If I were you, I would have been keep away from Netcup. Because I do it that way. Mazāk
