How do we check if pubmed.ncbi.nlm.nih.gov is down?
1) We check the pubmed.ncbi.nlm.nih.gov server to see if it is responding and we do this from a region closest to you. This test we perform simulates what an actual web browser (e.g. Safari, Chrome, Firefox) would do when trying to visit the website. 2) We determine if the pubmed.ncbi.nlm.nih.gov server is returning an error message that indicates some sort of problem. These types of errors generally mean that a visitor -- you -- would also have trouble using or visiting the service. 3) We return the results of our test from our servers and let you know if pubmed.ncbi.nlm.nih.gov is up or down. Coming soon - We are working on a new feature that will enable you to report problems and errors with pubmed.ncbi.nlm.nih.gov directly from this website. You will also be able to view what other pubmed.ncbi.nlm.nih.gov users are reporting and see past issues and outages.
