Hey, that roundabout is in reality a traffic lights T junction now, I drove through it last week. The road alignment in OSM was correct last week. Satellite imagery is showing a previous temporary layout of the road that was in place to facilitate construction of Intel buildings.
Also, a bunch of bus route relations have been split in two by this changeset.
I think this and osm.org/changeset/171318595 need to be reverted. It can be done manually, or with tools. I'm happy to help with that if needed.
