There are numerous reports that those using Blogger, Google's blog platform, are having issues with getting their content into the Google Index. A Blogger Help thread has numerous complaints about the issue, all starting sometime yesterday.
Here is what one said:
I have noticed that Google suspended crawling and indexing of contents from blogger blogs on custom domain.I have seen upto 10 other issues relating to crawling and indexing .
I have visited about 20 blogger sites on custom domains and noticed that last crawl of their posts was on 20th September, 2019.
A top contributor in that forum said he has notified Google reps about the issue. He said "Thanks, I've escalated this to the Blogger Team and when I hear anything I'll update this thread."
There are many complaints about this issue, it is unclear if this is a technical issue on Bloggers end or Google Search's end or something else.
Forum discussion at Blogger Help.
Update: Via the top contributor later on today, "Google have said they have found and fixed the issue and posts should start indexing again in the next 48 hrs."
