We need to set up a proper caching infrastructure for Maps (see T109162 and T125126 for details). This requires 4x servers in 4x datacenters (eqiad, codfw, ulsf, esams), so 16 Varnish servers. Specs of Varnish servers seem to be standardized, but I'm unsure of what they actually are...
Note: we might be able to repurpose existing hardware for this as we decommissioned the mobile cache cluster.
So the request is to allocate the 4 machines in codfw/eqiad/esams/ulsfo each to the maps varnish service cluster. These are already in site.pp with 'ex-moble' in comment within their entries. Brandon pointed out in IRC these are the hosts for this. He stated these were reclaimed some time ago from active service and held back for this potential project. These are
eqiad: cp1046, cp1047, cp1059, cp1060
codfw: cp2003, cp2009, cp2015, cp2021
esams: cp3003 cp3004, cp3005, cp3006
ulsfo: cp4011, cp4012, cp4019, cp4020
