The concierge told me yesterday that OSS was up in operations "for the next few weeks" effective Friday. Due to a mixed-up same day change I didn't have OSS on my connecting boarding pass but it didn't matter, the customs agents didn't mention it as they processed me.

While I had to wait about 5 mins on the shuttle bus before it started over to the domestic side, there was still a little time savings and definitely a huge reduction in hassle (no security to clear).

Too bad that the airport architecture didn't (and couldn't) anticipate these changes. It's definitely a mess in the International/US area for connections now, with criss-crossing pathways and tons of airport staff directing people and checking boarding passes.
