alt Hacker Newsthe time it takes for light to travel from los angeles to virginia is 12 - 16 ms, round trip is 30ms lets say - that is a noticeable delay, and it could be easily disproven that 80% of traffic is literally routed through VA
now.. could they just copy the traffic and send it to VA on a side channel? probably?

i used to work, 15 years ago, on a (permissive, not covert) monitoring service for a UK national public service, the NHS spine core. We used switches to mirror ports and capture traffic in promisciouse mode on a few dozen servers split across a few datacentres that all the traffic went througg. We had certs installed to decode https. We could get enough hardware to do this step easily, but fast enough storage was an issue, we had 1 petabyte of usable storage across all sitesn that could hold a few days of content. We aimed to get this data filtered and forwarded into our central Splunk (seperate storage) and also into our bespoke dashboards within 60s. We often lagged...
And how useful would this information be? srcIP:port_dstIP:port pairs with almost all traffic encrypted. Pretty boring from a sigint pov.
Instagram, YouTube, misc Web traffic, and torrents, with a side of minutae.
I'm certain the three letter agencies yearn for the days before letsencrypt was de facto.
