As the instigator of the longish Pulse8 thread, I guess that I am in a better position than most to comment on the issues and general health of Pulse8's TTB connections.
When I first joined Pulse8 I suffered relatively low single thread TBB speed test results, but the multithread speeds were always top notch.
It may have taken a couple of months to get there, but once Adam, the owner of Pulse8 was on the case things started to happen.
The bottom line is that whatever was causing the single thread issues has now been resolved. I do see some blips in terms of single thread performance about half the time, but nothing like what I saw before. A further speed test a couple of minutes later often results in both the single thread and multi thread speeds maxing out.
Pulse8 are a TTB reseller pure and simple, so only offer Billing and First Line Support services. What they do, they do very well.
If you have any technical issues, then these get logged with TTB for resolution.
Adam cares about customer satisfaction very deeply. He has to. When he takes out a FTTC contract with TTB, he is taking out a twelve month contract, so he needs you to stay for 12 months if he is not to lose money on you as a customer.
I am still with them because of the work they put into resolving my issue and because I don't see anybody at the same price point who can deliver the same bangs for bucks.
