All fairly calm at the moment. 77% mobile already...
As always happens the number of users drops as the announcement starts...
Then explodes in about 20 seconds.... wow! Thats a huge jump!
256K and growing...
Announcement ends... does it go up or down? Very much up! 384K and growing.
45K to 610K in 10 mins. I'm so glad we have an infrastructure that scales quickly! Still growing. 85% mobile!
Real time analytics just stopped. Topped out at 769K! I think we were heading for a million....
Well that's a real shame.
It's under these conditions that #webperf really really matters. 45K to 769K in 11 mins.. If you are serving too many non-critical (& unoptimised) assets, your users and your servers are going to have a bad time!

CDN was reporting 46,000 requests per second with 0 errors per second. 5.1 Gbps bandwidth out at the peak.
Spoke too soon! Now up to 88,000 requests per second 
The spike(s) from CDN data is incredible. Note the initial spike at the start, drops during the announcement then an even bigger spike once it finishes! Crazy amount of traffic.
Could be a contender for busiest ever period on http://GOV.UK ...

99% cache hit rate at the CDN. Fantastic work @fastly!
Just to give folks an idea of how busy it actually got. At 8pm the site hit:
⢠3,429,224 concurrent sessions
⢠3,185,115 concurrent "users"
No wonder real-time stats stopped. This equates to the busiest hour ever in the history of http://GOV.UK .

Note: GA is only loaded if you accept the cookie banner. If you ignore the cookie banner GA won't record your page view. So I expect the real figure to be much higher.
5M unique IP address + browser combinations hit http://GOV.UK between 8â9pm last night. Equating those to users (which is definitely not 100% accurate, but a reasonable approximation) == 7.5% population of UK. Goes up to 12% if you look at traffic between 8pmâmidnight.
Out of the 17M page requests made between 8â9pm (111M if you include assets: stylesheets, images, etc), we served 21 5xx errors.
