Can't Access Costco Wholesale - Troubleshooting Instructions

If the site is UP but you cant access the page, try one of the below solutions:

Browser Related Problems

Force a full refresh for the site. This can be achieved by pressing CTRL + F5 keys at the same time on your favourite browser (Firefox, Chrome, Explorer, etc.)

Clear the temporary cache and cookies on your browser to make sure that you have the most recent version of the web page. For instructions choose your browser :

Fix DNS Problems

A Domain Name System (DNS) allows a site IP address (192.168.x.x) to be identified with words (*.com) in order to be remembered more easily, like a phonebook for websites. This service is usually provided by your ISP.

Clear your local DNS cache to make sure that you grab the most recent cache that your ISP has. For Windows - (Start > Command Prompt > type "ipconfig /flushdns" and hit enter). For details choose your operating system :

If you can access a website at office or from a 3G network yet it's not working on your computer, it is a good idea to use an alternative DNS service other than your ISPs. OpenDNS or Google Public DNS are both excellent and free public DNS services.

Check our help page for step-by-step instructions on how to change your DNS.

Having Problems with Accessing

(iPhone worked when computer would not)
I cannot sign in or order anything on from my Macbook Pro using Safari. However, I did put my order through with no problems using my iPhone which is also Safari. I called Costco technical service telling them I could not order or sign in from Safari on my computer, and they only said, "Yes that happens all the time". Gee, really? That's all I got from Costco. Nothing.......

I am posting comment to Costco directly here:
I would recommend everyone do the same. Apparently their standard line is "Our website is up and no one else is having an issue, which clearly isn't true."

I've called costco several times, they tell me I am the only one it is my service provider. Internet provider came out ran test, replaced equipment and came back saying it is Costco's server blocking me.

Site has been down for 3 days for me with the following message. I called Costco to complain, but they don't appear to have access to create tickets to their service provider and allow for customer feedback. If you are receiving this error (as others have based upon the comments) call Costco and complain.

It seems that EVERY time I go to it first comes up with their US website and within minutes it ALWAYS switches to Costco Mexico. I don't understand why it does that. You would think that if Costco wanted customers to shop online, they would fix this continual ongoing glitch.

Sarah Violeta · 22 March 2014 - 11:45

The website is down for me too. My cart has items in it, yet it tells me it's empty and shows nothing. Can't proceed to check out for days now. Using a Cell Phone/ I pad/ and a Toshiba Computer and it works on none of them. :'(

I can log into the photo section, but when I click the link to 'Get Started' on a photo card, a message comes up saying 'Loading Album Data' and nothing else happens. I've tried this in 2 different browsers. I tried calling Customer Service and the line was busy. At 9:30pm. Which means that I can't possibly be the only person calling with the same problem.
