Responsive, helpful, knowledgeable, efficient
Nexcess provides the best support I've ever experienced from a hosting company and most other types of companies as well. Why? A few bullet points for your quick consumption:
-Responsive: Crucial when your site is down and every second counts
-Knowledgeable: They have all the answers and will teach you a thing or too if you'd like.
-Reliable: I can rest easy knowing they're there for our company.
-Cordial: Always friendly, never badgering about sales.
I recommend them with no reservations. They've got an amazing team with the brains and the work ethic.
