DIY-ers can do it today, OTA files expected shortly.

January 2018's security patch is available for supported Nexus and Pixel devices. Factory images for the Pixel and Pixel 2 family, the Pixel C, the Nexus 6P, and Nexus 5X are available at the Google Developer site and can be manually installed today, and OTA updates are expected to begin shortly.
