A few other location are referred to in Vigilante(#3.9). Bigfoot drops a big stack of papers on the desk and when asked what it is, he tells Will it is "Supply orders, repair requisitions and inventory reports" for that day. Will tells him "Okay, you know they're going to have to wait, 'cause there's too much else going on. The Grozny Sanctuary's been attacked by rebels, we're being audited in Norway... and they can't pay the electric bill in Asuncion..." - Grozny(Czech Republic), Asuncion(Paraguay)
In Sanctuary for None Part 2(#4.13), we learn that there were at least 15 Sanctuaries near the end. Abby tells Will that "Tokyo, Dallas, Brisbane and Cape Town. All just listed their facilities for sale or lease." He reponds, "Four Sanctuaries closed. That makes 12 in the last eight months. It leaves London, New York, and here." Edit (Coming Soon)
