We have address ranges that are being blocked by sites like Ticketmaster. Customer support is able to assist, and unable to receive a response from legal or hostmaster emails. What are the recommendations for requesting a removal from the blocked list at these sites?
To make matters worse, many sites use CDNs with Web Application Firewalls.
The WAF is under control of the site, but many sites blindly implement the recommendations of the WAF provider.
So this allows the site to blame the CDN because they blindly implement their recommendations, while the CDN states that they cannot fix it because the WAF configuration is under the control of their customer.
This was a persistent problem when I was at Akamai and has not been solved there yet to the best of my knowledge. Virtually every other CDN/WAF provider works the same way in my experience.
I have heard tell of a CDN / WAF that is generally held in good regard having a free tier that many people use that is much less flexible than the paid tiers. As in things are enabled by default and you can't disable them. -- I have no first hand experience with said CDN / WAF save as a consumer behind such CDN / WAF.
