NCBI Begins HTTPS Tests

You may have heard that NCBI, along with the rest of the Federal Government, is switching to HTTPS-only access. To help prepare for this, NCBI is beginning a series of tests. During these tests, all traffic to NCBI will be redirected from HTTP to HTTPS to simulate our system’s behavior once the HTTPS transition is complete.

The first test will be Thursday, September 15, from 8:00-9:00 AM EDT.

If you experience problems with any NCBI site or service during that hour, please see our Secure Website Tests plan for advice on how to proceed.

If you use software that accesses NCBI data, and you experience problems with that software, we recommend that you contact the software vendor, as they may need to update their products to work over HTTPS.

If you use proxies to access NCBI (for example, EZProxy) and you experience problems during this period, we also recommend that you contact the proxy service to ensure that your service is ready for HTTPS.

If you develop software that accesses NCBI services or that depends on NCBI APIs (such as the E-utilities) or toolkits (such as the SRA or C++ toolkits), these tests are a great opportunity for you to see how your software will function over HTTPS.

  1. Great today most of the websites are moving to https. It is more secured server option, it is beneficial for users and builds good trust among users and search engines.
