Yelp.com blocked from my work address

Yelp.com is blocked from my work internet. Not by any filtering on the part of the office (it is a shared office building with shared internet.) My wild guess is Yelp banned the range of IP addresses from the office because maybe some other tenant here was abusing the site? Or maybe some DNS or something else is just whacky and broken? It is nothing on my laptop, the same laptop can access Yelp.com fine from my home internet.
