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. :) Royce
