Outlook.com forgot how to filter spam this morning

When I got up this morning the inbox had more than double the number of emails I would expect.

Most of them were easily identified as spam that usually ends up in the spam folder. (I have a lot of repeat offenders in the spam folder, so those were obvious.)

When spam filtering is working, I still have to check the spam folder every day or two, because usually outlook errs on the side of labeling non-spam emails as spam.

Just curious to know if this was a widespread issue today, or does MSFT just hate me?
