They are microcosms of larger areas - think gamers, B2B, local
support/RDP, etc.  When there's ~25ms extra latency ANC<->SEA, every
little bit helps.

It also lets us function locally when there are major external outages.

Finally, there's a psychological benefit. It drove me nuts to have my
traffic shipped to Seattle to end up literally one block away.  :)
It's like when I tracked my Macbook from China -- stopping briefly in
its palletized/containerized form in Anchorage on its way to Kentucky
(UPS distribution), and then back to Anchorage ... days later. :)
