I emailed IANA (Internet Assigned Numbers Authority) earlier today to ask about the new content on example.com. To my surprise, their VP replied. Here is the email: I am happy to try and answer any questions you have. The changes we make to the site from time-to-time are usually informed by a desire to either reduce the overall bandwidth demands of serving the site, or improve its utility. At its heart it is a placeholder...
I didn’t take any overhead in account, just checked that the site itself was a bit under 2kB worth of data. 1 gigabit / 2 kilobytes = 62500, so in order to consume 1Gbps you’ll need about that 62k visitors every second. Handshake is few hundred bits and other overhead is pretty neglible, but those are still not zero so I just rounded it down for a rough ballpark number.
Thank you
