I noticed the problem with the Datacache resource this morning too, and we are currently looking into it. More soon about this!
But I’m wondering if there is a specific reason why you need to use the local version. This genome was sourced many years ago from a now deprecated version of a microbial browser hosted by a UCSC group. The chromosome name was abstracted to simply “chr” if I am remembering correctly. This makes it unsuitable for certain types of analysis. We keep it as a legacy/reproducibility resource for some early analysis projects.
If you plan to incorporate this genome with an annotation file, getting both files directly from NCBI, in the current public versions, and using those with tools, is sometimes a more robust scientific strategy.
Is you data already processed (which tools)? Or are you at the start of an analysis? I can help to advise depending on which step you are at in the analysis processing.
