Due to circumstances beyond our control, the Los Alamos E-print Archive will suspend the ordinary database updates and mailings on Monday and Tuesday the 21,22 June 1999. This is to comply with a DOE directive (exerpted from the publicly available LANL Newsbulletin 6/17/99):
Secretary Richardson has asked the management and employees of the three Nuclear Defense National Laboratories -- Los Alamos, Livermore and Sandia-- to undergo a two-day security immersion program June 21, 22. All normal operations will cease at the National Laboratories during this period as the employees will participate in an intensive review of personal responsibility for security, counterintelligence and cyber-security.
While xxx.lanl.gov is in the open laboratory network partition, and is not directly related to any sensitive information or other security issues, it is nonetheless subject to the two-day ``security standdown'', a Department of Energy directive that applies to the entire laboratory regardless of the nature of the work involved. This will constitute the longest such unplanned interruption in the archives' otherwise round-the-clock continuous operation since August 1991. (A collaborative arrangement to establish a new US mirror, currently under negotiation with the University of California Digital Library, might help bypass any future such problems through the new arXiv.org URL.)
Items already in the database will remain fully accessible during this period, and submissions will continue to be accepted as usual by the automated input routines, but all new submissions and replacements during the period 19-23 June will not be made publicly available until the 23 June regularly scheduled e-mailings. Fri 18 June submissions will be announced as usual on Sun 20 June. Any e-mail concerning administrative matters will also go unanswered during the period 21,22 June 1999 (and there may be some additional delays until the backlog is cleared).
