Earlier today I asked TWC's Tech Support about Astoria's still-in-use IntelliSTAR 1, and this was the response that I received from Tony:
Jim - According to our records, Charter Astoria has already switched over to the I2 star back on 10/12 for the SD service. The look of the local would not change much, the difference is very slight.

So, it appears that Astoria
does already have an IS2, but for some strange reason, I'm still seeing the IS1 feed where I am, across the river in Pacific County.
I'm guessing maybe Charter hasn't switched to the IS2 feed up here yet, but they have already for the viewers down in Astoria and neighboring Seaside.
