For the average end user using their ISPs nameserver, it's... well,
out-of-scope. But MBIX isn't for individuals, it's for ISPs and
enterprises who want substantially-enhanced connectivity.<br>
If you run your own recursing resolver, however, whether because you
don't trust your ISPs, or you are an ISP yourself, there's a direct
correlation between how quickly you can get an answer from a root NS
and how quickly you can get the answer back to the end-user.<br>
Without MBIX, the closest root nameserver most Manitobans have
access to is typically 20-30msec away from their ISP. Ditto for .CA
nameservers. (The PCH and CIRA D-root servers also host a bunch of
gTLDs, IIRC, don't know which.)<br>
So while caching helps a lot, that cached data does expire
frequently. <br>
Consider how many HTTP requests are involved in loading, say, the
Facebook homepage. Consider how many of those go to different
domains. Now shave ~10msec off (potentially) every single one of
those DNS queries.<br>
By the time you multiply it out over a day's work... times an entire
ISP's worth of customers...<br>
Better DNS is kind of like having better plumbing in your building.
No-one thinks about it: as long as the bathroom *functions* everyone
can get their jobs done. But having better-working sinks, toilets,
etc. adds up to just a tiny bit smoother experience, and those
seconds saved do add up over time.<br>
<br>
Plus, it also means you can still browse the 'net when the root
nameservers are being DDOS'd again :-)<br>
