I don't feel particularly inspired by XLN under normal circumstances to write a review but I found these reviews by chance and they're so far removed from my experience that I felt it necessary to write a review.
We have an office in a rural location so we could only access ADSL. I chose XLN for a business line to ensure quality of service compared to residential. The line itself has been problem free for over a year. They charged exactly what they said they would and we receive slightly higher speeds than they said we would.
They periodically call to try to sell something, which is very annoying, but as a service, I have very little to gripe about.
