Confirmed that the A power feed seems to be down. We've reached out to other hosts in the Chicago deployment, and they've confirmed they lost their A power feed too. B power remains online, however single PSU servers (Ryzens, E5-1650s, single PSU colocation on the A feed) will be down. We've opened a ticket with the building to inquire about an ETA for restoration, and will post more details here.
