What To Do If ncbi.nlm.nih.gov Is Down
Troubleshooting Instructions
If the site is UP but you can't 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.)
- Try alternative urls such as beta.ncbi.nlm.nih.gov
- Clear the temporary cache and cookies on your browser to make sure that you have the most recent version of the web page.
Fix DNS Problems
A Domain Name System (DNS) allows a site IP address (192.168.x.x) to be identified with words (domain.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).
- 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.
Server Issues
If the site is DOWN for everyone, there's likely a problem with the website's server. Here are some common reasons:
- The server is down for maintenance
- The website is experiencing too much traffic and the server is overloaded
- There's a programming error on the website
- The domain name expired and is no longer active
In these cases, there's nothing you can do except wait for the website owner to fix the issue.
