Did anyone consider CDN for pics? Srsly,even 250,000 people hitting at
10kbps is 2,500,000,000 bps or 2.5Gbps. 10kbps might only barely suffice
for static HTML at that rate.

An apache web server starts to struggle at 500 SIMULTANEOUS requests,
meaning 250,000 visitors would need to be load balanced across 500 server
instances, assuming your LBs can handle that amount of sessions, keep track
of the backend servers, which likely multiplies the traffic to double the
request amount, and that is just to ensure a 10kbps experience without any
pictures, and static HTML/js.

500 servers running any type of PHP or ASP or god forbid anything Java and
forget it.

CLICK CLICK BOOM

More than likely Telstra and Optus saturated someone's interconnects,
there's not too many people with lazy gig links hanging spare about the
place.

Indeed, even something as simple as cloudflare can turn a fail-site into a
world-class one with a few clicks. Obviously not the case for every site,
but even just the caching provided that reduces network utilisation (which
I believe is what is the cause of this outage).
