I have worked with sooo many webhosting providers over the years ~ 1&1, Strato, Host-Europe, Mittwald, IP-Projects and several smaller ones to just name a few. I’ve been so impressed with all-inkl.com lately that I’ve moved several projects there and became a partner. Here’s why.
I would not recommend anything to you I’ve not been using enthusiastically myself. Bold links are affiliate links. I recommend what you’ll find there and If you make a purchase, I will get a commission without additional costs to you.
Features
There is a members area meant to manage profile, contracts, bills, etc. and a customer administration area meant to manage domains, mail-accounts, ftp-users and the like. Everything looks clean on the brink of rudimentary which tremendously helps in navigating through the bulk of options we got there. While the members area is available in German only, the administration area (KAS) features German, English and Polish. I’ve been able to handle every single one of my clients requests so far. Routing mail-accounts through to Office 356’s Outlook/Exchange? No Problem!
They have been among the first to implement free Let’s Encrypt SSL certificates. Those could be used from their PrivatPlus tariff and up. You can even edit domain DNS to rerout let’s say a mailing-list-links to your own TLD.
Reliability
Absolutely nothing to complain about here. I have yet to see them unavailable after 2 years of service. Their network is fast and reliable at all times.
To me, reliability and speed is what really counts when it comes to webhosting. I’ve had providers constantly unable to handle high traffic and/or dos-attacks. When working online, it’s more than inconvenient if you have to wait 30 seconds for each change to be applied to that CMS you’re supposed to fix. Your client will most likely not happily pay more when you needed four times the calculated effort because of its slow and unresponsive provider.
Support
They leave you alone unless you ask for support via phone or mail. Then their response is fast and competent, albeit not super friendly. But maybe that is just service-desert-germany-style, right?
And here is a poll I did on 17.10.2017 in my local WordPress Facebook community. I had asked my fellow WordPresseers about their favorite webhosting provider. This turned out much more unambiguously than I expected.
