PureVoltage is amazing, I am a client with LevelOneServers which was recently merged in with PureVoltage, and I have nothing bad to say about the two companies.
The services are very fast and reliable, and have amazing prices that fits to the expectations and specs of the services they provide.

The staff and IT team are very experienced, they are fast at getting things fixed, and very fast at responding to tickets.

I highly recommend PureVoltage/LevelOneServers.
