Please see the following announcement from NCBI, which will affect access to Pubmed and other NCBI databases:
On Friday, July 25th, starting at 9:00 PM EDT, we’ll be performing essential maintenance on the NLM data center. This upgrade is critical to ensure the continued reliability and stability our services.
We anticipate this planned outage will last 24 hours or more. During this time, users may experience interrupted access or degraded performance across a range of NLM resources, including databases, search tools, submission systems, and programmatic services.
We understand this may cause inconvenience, and we sincerely apologize for the disruption. We’re committed to minimizing impact and will provide timely updates throughout the process.
We expect all NCBI products and services to be fully available again by Monday, July 28th.
