Eh, maybe your company' vpn is better than mine, but I do as little work as possible on the VPN due to abysmal speed.
Slightly maybe but split tunnel would avoid that. If it was full I'd expect to see an increase from popular cloud hosting regions (if it was a prod vpn) or if corporate VPN's their home offices (which would show as a net zero change)
AWS has a large data center near Portland... (And Washington DC for that matter)
