I2B Networks

I was at Castle and AIS before moving our servers to I2B about 6+ years ago. I saw that there was a single 1 star review so I thought I would share my experiences with I2B.
I moved to I2B because I wanted to work with a provider with a more family like feel that still had the technology required for me to feel comfortable moving and running our server infrastructure from their facility. I have had nothing buy great experiences and they have always been accommodating.
I recall one network outage over the past 6+ years and 0 power issues, even when San Diego lost power. The network outage was remedied that day and has never been an issue since.
I recommend you check them out for yourself and compare them to the other big players to see who fits your own needs best.
