Said It Here

Why is my website silently blocked without any notification?

Gateway security providers often block domains without notifying the site owner, leaving sites completely unreachable for users on specific networks like Xfinity. Because these blocks bypass standard blacklists and provide no alerts, owners only discover the issue by accident, which prevents them from diagnosing downtime or restoring access for visitors.

“We built a site for a launch and it was unreachable for anyone on an Xfinity router. We only found out because we have an Xfinity router at home. There's no notice to the site owner.”source ↗

“I was helping a client get their domain delisted from SURBL and noticed that LinkedIn was blocking the company's website link on their LinkedIn company page.”source ↗

“It turns out if the domain is listed on SURBL, LinkedIn redirects all website visitors to a warning banner - they literally replace the website URL with a LinkedIn / suspicious link one”source ↗

“And if the domain is listed on SURBL for too long, Google will index it and make it searchable for the public.”source ↗

“So technically marketing teams messing up their emails makes leadership put pressure on IT teams to fix it!”source ↗
