Why is the "Activities behind" count between us and Lemmy.World increasing?

https://grafana.lem.rocks/d/edf3gjrxxnocgd/federation-health-activities-behind?orgId=1&var-instance=All&var-remote_instance=lemmy.ca&var-remote_software=All&from=now-24h&to=now

Decided to check out the site above and I'm not sure if I'm reading things correctly, but it looks like we're running behind Lemmy.World by a significant amount compared to the other major instances. I'm also noticing the scores of my posts in a Lemmy.World community is not updating despite receiving upvotes.

Anyone else experiencing similar issues or any odd issues in general?
