It's interesting how NextDC and Equinix differ in their security.
Equinix has airlocks, NextDC has individual pods that sometimes even work.
Equinix will send alerts about planned maintenance. NextDC does too, but they require explicit acknowledgement of receipt.
Equinix's security desks are always staffed during office hours, and pingable after hours. NextDC's desks are a crapshoot.
Both are light years ahead of Vocus, but that shouldn't come as a surprise #ausnog
