We had some very unexpected behavior from upgrading the JSON serializer which wasn't actually deployed until APIv2 was built today...for a few minutes it was throwing some very unfriendly JSON with surprise properties.

That's been corrected (reverted) and the cache has expired on stackexchange.com, so all should be well now.

  • Is this caused by the same unexpected behavior? Commented Jun 16, 2012 at 21:18
  • @ShaDowWizArd - nope, that was during a backfill today to sync things up...though the not handling that gracefully on SE.com (now that the accounts tab is there only) wasn't on the radar...it's slated for a fix now Commented Jun 17, 2012 at 0:39
