Well, I dont know the exact specifics of the company. But Im sure they run on multiple T1/T3 lines, if not fiber-optic. The companys name is Cyberwings. So far they have proved to be very fast and reliable for me. I also know a few other people who have hosting plans through them. Since my site is generating very little traffic right now Im only paying for a 6gb per month transfer limit with 120mb hdd space. Their rates are VERY cheap for low traffic domains or high traffic domains. Their most expensive AYW hosting plan is $155 per year and that includes:
144gb per month bandwidth (I read contour.org is only using around 100gb per month)
72 databases
full dns rights
650mb disk space (this should cover the size of the database)
72 subdomains
This should easily be enough to host contour.org. If more is needed, I know they will work with you to get you what you need. $155 would not be hard to raise from donations. It would only be a matter of transfering the site over to their servers.
