Hi, folks!
Sorry for the latest instabilities in the instance. For some reason we were getting spikes of 100% every now and then, and that would make the instance unstable.
I just finished upgrading to 0.18.3, which was released today. There should be a lot of CPU improvements since 0.18.0, so hopefully the instance will be more stable from now on.
Let me know if you encounter any problems! Since we're usually in the dark during instance upgrades I created a Mastodon account for the instance, so I can post status updates. You can find it here: https://mastodon.social/@lemmystudio
