Funny, I am dealing with the same issue, you are not alone! Reverse lookup on their IP shows that it is hosted by Akamai. I have reached out to them, but the issue hasn't been resolved yet. I have had issues with Akamai black listing our IPs in the past, it has taken 1-2 weeks to get it fully resolved normally.

Hello folks, I'm grasping a bit at straws here, and really hope maybe somebody has some knowledge that may assist in getting an answer where we've been met with silence. We're a small isp who unfortunately is dealing with our entire range of IP blocks being restricted on what appears to be a permanent basis from TicketMaster's services. We've attempted all avenues available to reach out to them, between their NOC contact and their... client support contacts... to no avail. Unfortunately, the ones caught out in the cold at this point have been the end users who as a result cannot utilize Ticketmaster... I'm hoping someone can offer some insight if they've been down this path before, or further, if you're from Ticketmaster, contact me off list to trade coordinates so we can resolve this quickly. Thanks! -- Ryan Gard
