SRE Weekly Issue #345

SRE Weekly is now on Mastodon at @SREWeekly@social.linux.pizza! Follow to get notified of each new issue as it comes out.

This replaces the Twitter account @SREWeekly, which I am now retiring in favor of Mastodon. For those of you following @SREWeekly on Twitter, you’ll need to choose a different way to get notified of new issues. If Mastodon isn’t your jam, try RSS or a straight email subscription (by filling out the form at sreweekly.com).
