If you cannot get to accounts.sketchup.com, it’s your network. Please do not get snippy with us because we’re not fixing YOUR network. I have fixed people’s networks before:
The Comcast issue was debugged by me when a school for kids on the Autism Spectrum could not get to 3dwarehouse:
Some Comcast customers were unable to connect to 3D Warehouse from the SketchUp client and the behavior was attributed to “smart packet protection” setting on the Comcast router. This “protection” was an extra layer of blocking or security for Comcast customers. It was a feature that Comcast implemented on all customers, but had since disabled on all (oops, I guess not, because I found this) customers because there were many problems with it. So, if you are unable to 3d Warehouse and still have this setting enabled on your Comcast router please disable it and try again.

This resulted from people telling us 3dwarehouse was broke, and so I diagnosed that it was a DNS problems for end users on the ISP, British Telecom in the UK.
And you think YOU’RE repeating yourself? Please solve your network problem and report back here and we’ll add it to the list.
