My wife told me that yesterday she was unable to access amazon.com and citicards.com. I checked on my laptop, and I couldn’t access them either. I did everything I could think of, including deleting the cookies, rebooting the router, resetting the router, closing and reopening the browser, trying different browsers, and rebooting the laptop - and several combinations of the above.
After I reset the router, I am able to keep Amazon up for about 15 minutes, then it gets a connection reset error. Citicards now works fine.
I am running Windows 7, and we’re located in Israel (although that shouldn’t matter). I did have a neighbor check to see if she could get on the sites, and they worked fine for her. Also, we’ve not had any other problems accessing any other websites. I work for a client in the U.S., and have not had any problems accessing any of my work websites.
It sounds like you might have an issue related to DNS. This article goes over a few things to look over, but in particular try this bit:
(Assuming Windows) To get to where you need to type that command, go to the “Start” menu, click on “Run” and type “cmd” and hit <enter>, then type in what it says to above and try going to the website again.
Must not be a DNS issue then. Maybe some sort of routing issue with your ISP. Does your neighbor that wasn’t having any problems have the same ISP? If not, I’d try calling your ISP and see if they’re aware of any issues.
