My domain is blocked by Watchguard
I am a virtual tour website creator. Most of my customers are in one form of government or another. I was notified in January by one of my long time customers (a Community College in Kansas) that their Watchguard firewall was blocking access to the virtual tour web page that I have hosted for them for 10 years on www.photographyoptions.net. The block message categorized their link from my server as a "compromised website." Their install of the Watchguard firewall was not new, and the problem seems to have started with some type of update. A few weeks later, I made a sales call and found another government org. in SC that experienced the same problem. My hosting provider, A2hosting has a assured me that there were no blacklists associated with my IP address. I would like to find out how my domain ended up on the Watchguard blocklist, and how to get it delisted. Any advice on how to move forward with this will be appreciated.
