Ask HN: Google Voice Call History Missing?

Yesterday afternoon I was looking at my Google Voice "Calls" tab to get the number for a call that came in a few hours earlier, when I noticed that all calls after Sunday afternoon (3:50pm PDT) were missing. I seem to be missing about a dozen calls now, and they were all showing as recently as Tuesday at noon. They aren't in the archive, and everything else (Messages, Voicemail, and Spam) is still there. It's not a browser issue because the calls are missing on my Android phone and my iPad as well as a desktop browser.

I've found nothing about this in the news or elsewhere on-line. Has anyone else experienced this, or is it just me?
