It says that it's "DDoS protection software provided by Cloudflare". DDoS works by bombarding servers with sheer weight of numbers of requests that outstrip the server's ability to handle them. Just as physical security searches at airports, sports, entertainment and political venues usually reduce the number of entry points and slow the throughflow of entrants, DDoS protection SW throttles server access. I don't know who TC's new owners are, or if TC has new owners, what other internet assets they have, or whether those might be vulnerable to denial of service through the TC forum server, but I have seen it before. This Cloudflare outfit might even be the new owners, touting their wares through this server rigmarole. Although, if you check their site, it proudly declares that it makes your *insert entrepreneurial-sounding internet jargon and acronym soup here* "faster and safer". If this is "faster", I wonder how their definition of "safer" is qualified?
