It’s a wide-area madness. People have been reporting the site: operator problems for a few months now.
Even now after some time of the Sitemaps’s team statement which said all is fixed, people are having problems.
At SEW, some say it’s only for directories, but it’s so NOT. All kinds of pages are affected. Even 4 or more years old domains.
And now I notice that some of my websites have yet again 500 pages indexed (out of the 16.000 or more real ones), and 130.000 pages that I physically removed from my server one YEAR ago, are showing up as indexed.
Don’t get my started on other issues like the link: operator.
