The IUS Community Project (https://ius.io/) has transitioned from using a network of mirrors, to using Rackspace's CDN service.
MUUG's copy of IUS has been renamed to "ius-legacy" on our mirror, and has been synced one final time (there were no changes). We'll delete that, too... eventually.
Moving forward, if you have an up-to-date version of the "ius-release" RPM package, you'll automatically be redirected to use the closest mirror.
If you have an obsolete ius-release installed (from before April 2019, roughly), and/or you've manually customized your .repo file to point to MUUG, you'll now be getting 404 errors. Install an updated ius-release RPM (see https://ius.io/GettingStarted/) to get back into sync with the new CDN distribution.
