git.llvm.org</a> would be maintained for a year after the transition to the mono repo. I don't recall where I got that impression from; probably from some of the many emails on the migration topic. I noticed today that updates to these repos ceased on October
22nd of last year following transition to the mono repo. Was I simply mistaken that these repos were not going to be maintained along with the (read-only) svn repo? We had not planned to complete our own transition to the mono repo until a little later this
year, but if these repos are no longer maintained, we'll have to readjust our priorities.<br>
