Hello again,
 
Thank you for all the information you sent to me after my original posting.
After hearing some "not so good" opinions regarding Genuity, I'd like to slightly rephrase my question:
 
There's a report at ispworld http://www.ispworld.com/isp/images/geometric_mean.gif
From the test one can see that first 14-20 positions are very similar in performance, so what's important for us is virtually no downtime (not in SLA, but in reality) and quick tech support response to troubleshoot the problem (ICG doesn't have tech in their POP in Newark...)
Now aside from the test,  would YOU recommend one provider or another based on your OWN experience?
I don't think any public resource exists which compares reliability of backbones, including last mile link - how stable are the routers that handle your particular T1...If it does exist, I'll appreciate any pointers.
We experienced a lot of problems when ICG Newark POP went down on couple of occasions and they don't have a redundant link to anywhere else....
 
Thank you very much for you help.
