I believe that sw.lsstcorp.org, the prior home of the LSST Science Pipelines source and binary packages for eups distrib, has been unused since at least March 2017, when it was replaced with eups.lsst.codes.
I am proposing in RFC-549 that we retire that domain name, which is maintained by Tucson IT rather than SQuaRE.
If anyone has objections, please reply here or on that RFC.
