I'd be terribly interested to know how you obtained these figures...we do
web hosting services as well. I had one of our clients complain angrily
for weeks that his web site was frequently "down" because he couldn't get
to it from AOL. I had to sit him down and show that his site was
operational and accessible from a dozen other sites to convince him that
AOL was the exception, and that our connectivity and server reliability
were not to blame.
I find it hard to believe that many providers could offer only 98%
reliability (assuming, of course, that this is a measurable quantity;
this is shaky ground); this implies that over an average period of 100
hours (less than 4.2 days), there exists a total of 2 _hours_ of
"downtime" (assuming, again, that this, too, is determinable in any
meaningful sense).

Do you take the customer's word for it?

I think the reason for this is obvious. If a customer complains that
your network is unreliable because he can't reach it from point X, do you
give him a refund? Not all of us can afford that...I know we get more
than a few complaints of this type every month.
