Just a heads-up for anyone who prefers 1-year validity over Let's Encrypt's 90-day cycle. I noticed ServBay is giving away 1-year DV SSL certificates for $0. It uses the Certum root.

How to get it: Go to the store: https://www.servbay.com/store

Scroll to the very bottom. Select the $0 DV Single option. They mentioned it's limited to the first 1,000 users. Hard to beat a price of zero for a paid cert, so I thought I'd share.
