It’s refreshing to find a host that runs their own servers. How can you tell? They offer services like co-location. Co-location means your servers are physically located in someone else’s facility. This can be very helpful because the attention and time required to keep servers running smoothly is pretty significant.
AISO.net (Affordable Internet Services Online) offers co-location services as well as the basic hosting accounts common to the rest of the green web hosts listed on this site.
