No, they had 30M:

This right here is why you can discount most replies on HN right off the bat. The "I can make software X in a day" posts are 99% bullshit because the posters making them have idea what business reality look like. If their program gained any popularity they'd be in a panic the first time the FBI dumped a warrant in their lap and their full stack developer is now spending a week with the lawyer trying to figure out how to untangle their data while the customers that paid for ads are yelling the metrics API went down 2 days ago.
IG 13 employees at 30m users. Couldn't find # of servers.
FB had 10k servers in 2008 and 100m users, 850 employees.
I believe Doubleclick had ~500-1000 servers for ~10b daily impressions in mid-2000s.
Those numbers are all on circa 2010 hardware, so.. divide by a decade of performance doubling every 2 years (conservatively), or ~5x fewer servers in 2020.
The government takedown stuff, from personal experience, is tiny on the systems side; much more about moderators and expensive legal staffing.
These are very rough estimates, but I've heard 250k servers for Twitter.. that's much more on par with Goog/Amzn/Msft serving clouds at ~1m+ machines. That's a mystery to me.

What tooling do they provide for governments?
