Well it appears Google has gone from image verification on searches to just flat out blocking the Dallas servers now.
403. That’s an error.
Your client does not have permission to get URL /search?client=firefox-b-1-d&q=google from this server. That’s all we know.
This has developed into a more robust issue and is not just a Google problem anymore.
If anyone is being blocked on a different site while connected to any Dallas server feel free to post and I'll update this thread.
