We're hosting multiple server clusters at Vautron Rechenzentrum AG. The support is the best we've ever had, tickets are usual...展開
ly resolved after some hours. Network performance is great (no outages during the last years). The prices for our servers, clusters and domains are very fair. The best thing is that they do not charge additional costs for their great support.
To sum it up: We're very happy with Vautron and can highly recommend them!
