Always On The Ball
We've been with Nexcess for more than 5 years. We operate primarily out of South Africa - though are more than happy to have hosts in the US (they're reachable 24/7/365 - so even with the timezone difference, they're super responsive!)
The level of efficiency & professionalism simply is world-class.
If you're looking for a reliable hosting partner who truly cares, helps and is always there to assist when needed - look no further than Nexcess.net, the wizards of Magento hosting.
