Adam,
ip2location.com has that IP block listed as "(DCH) Data Center/Web Hosting/Transit” which we’ve seen cause issues for residential users in the past, most notably on Cogent IP space.
We worked with support at ip2location.com to have the address block re-analyzed and updated to "(ISP) Fixed Line ISP” which resolved many of the issues users had accessing various streaming CDN services.
