I find the tabs on the Explore page return errors about 20% of the time. Also, yesterday Trending was offline for an hour or so, and random keywords like Telegram were blocked and then unblocked [1]. It's about as broken as you'd expect for a company that just lost ~70% of its headcount.
Edit: figured it out - content filter on the wifi I was using was filtering out some but not all Twitter URLs. It’s always DNS, I should know better.
