Relayed by the NN/LM SCR:

NLM now provides an e-mail notification service, PubMed Alerts, that will notify subscribers of major system problems with PubMed; its two companion databases, MeSH and Journals; and the NLM Catalog. If these databases have a significant service disruption affecting all or most users for a considerable amount of time, an alert will be issued. Alerts providing update and resolution information about a problem will be sent if warranted. This is an announcement-only e-mail notification service that will be most useful for heavy users of PubMed. (It does not include other services/databases, e.g., LinkOut, PubMed Central.) Alerts will be sent out by NLM Monday through Friday, 8:30 am to 5:00 pm Eastern Time (except Federal holidays).

To subscribe, send an e-mail to pubmed-alerts. Leave the subject line blank and enter "SUBSCRIBE pubmed-alerts [your name in the body of the message]", e.g., "SUBSCRIBE pubmed-alerts jane doe".
