Ask HN: Any idea why Grok hasn't responded to any tweet for more than 3 hrs now?

I have asked it a few verification questions in the past few hours, no response. I then checked its last activity responding to any tweet, and there hasn't been any for more than 2 hours now.

If you use the main link to grok, it answers, but it is not responding to tweets when it is mentioned.
