How big is the largest strongly connected component of the web?

I'm not sure if this is the right place to ask, so tell me if you think there is a better subreddit

According to this link: http://www9.org/w9cdrom/160/160.html the main SCC of the web was over 50M pages in 1999. Is there any source that tracks this currently?

Would scaling 50M by some growth factor provide a reasonable estimate? I'm not sure if this is a valid thing to do on SCC because the number of interconnected websites is not necessarily proportional to the total amount of information on the web...
