Working for me. Are you from the Middle East or something because there was the issue with several submarine cables which connects the region to the internet backbone was cut and they are in the midst of reparing it. http://edition.cnn.com/2008/WORLD/meast/02/01/internet.outage/index.html
I'm not from Middle East but from Europe. If there was such issue I guess I may not access other sites as well.
Paypal is ok for me too. Can you try to do a tracert on Paypal and maybe post it here, maybe some of us can help solve your problems?
