Ok, there are three problems going on. First, the site has been intermittently super slow. This is happening because of some database locking conflicts and long running queries. I don't have this fully mitigated yet, but I know what I need to do and just need to get it scripted so it can recover automatically and gracefully.

My attempts to solve the prior problem broke federation by causing the messenger services to think they didn't have a connection to the database. This should be fixed now, and now that I know it happens, I can mitigate it in the future.

The other problem is with only being able to go back one to three pages (some times the first page is all you get). This is a known issue in the new version of mbin and the devs are going to revert the pagination scheme to the prior version until the bugs get worked out. In the mean time, if you click on "combined", you will be able to go back for miles (or kilometers).
