[R-pkg-devel] Windows binary package not at mirrors

I received this message 3 days ago:

Your package BiasedUrn_2.0.12.tar.gz has been built for Windows and
will be published within 24 hours in the corresponding CRAN directory.

However, when I try to load the package, I get this message:

Do you want to install from sources the package which needs compilation?

If I say yes, it compiles the package on my computer, provided that I 
have installed the compiler. If I say no, I get the previous version of 
the package.

The Windows binary is at 
https://cran.r-project.org/web/packages/BiasedUrn/index.html , but not 
at the mirrors.

Is the Windows binary version of my package delayed, or has it not been 
sent to the mirrors?
