Abstergo had animus technology spread throughout the corporation and had only been developing it since the 80's. HYDRA has theoretically had at least rudimentary abilities since the 40's. They've had SHIELD's resources nearly that entire time.
Given the targets we could possibly link to him in that time period. I'd place one at least near where we would find major SHIELD facilities to ease deployment. It's what I would have done.
