I can't find references to them under operations/puppet, operations/mediawiki-config, or cloud/instance-puppet. We seem to use 0[45] with 08 as a buster testing machine.
They run Jessie and I've been looking at the parent task wondering why we have so many memc boxes.
If they're not needed can we shut them down / terminate them?
Tyler: It looks like you made these in late November 2018. Any ideas?

This suggests that four servers (memc04 through memc07) are currently in-use by appserver/nutcracker for Main Stash (incl. legacy sessions).
It seems that memc08 (Buster) is newer and not in use.

It looks like I added memc05/06 so that @aaron could test mcrouter replication (per T175418: Create new instances memc05 and memc06 running memcached). Not sure why 07 was added offhand.
