Google has another bug, this time with Google Search Console's crawl stats report. The report has a gap in the data, missing data on November 19th and November 20th. Google's John Mueller confirmed the issue and said on Twitter the team is working on a fix.
You can try to see your crawl stats report over here and see if you have the same issue.
Here are some charts I pulled to show the two days of missing data:
John Mueller said "It looks like a bug on our side (it's just a reporting issue, not related to anything else). The SC folks are working on it."

So hopefully it will be fixed soon.
Forum discussion at Twitter.
Update: A day later this is now fixed.
