Computer Downtime on May 16, 2010

On Sunday night, May 16, 2010, the network and server teams will perform our normal monthly system maintenance to all servers and network equipment.

The downtime window will last from 5:00PM – 1:00AM.

This downtime was moved from the normal Thursday evening to prevent a conflict with the academic calendar.

The following services will have one or two small outages:
(You can continue to work, but may have brief pauses while services restart)

  • GroupWise Full Client and IMAP Clients
  • Novell File and Print services
  • NetStorage
  • ICF File and Print services
  • OASIS
  • ALICE
  • Powerfaids and NetPartner
  • Web Server (main www.hsph.harvard.edu site)
  • GroupWise WebAccess
  • Accellion 

The following services will not be affected:

  • HPCC system
  • HSPH Unix server
  • Network connectivity for all of SPH. This includes non?HSPH Web sites
  • Network connectivity for SPH 1
  • Network connectivity for SPH 2
  • Network connectivity for FXB
  • Network connectivity for Landmark Center
  • Network connectivity for Offsite Locations
  • HSPH Wireless Network System

All future planned down times are Thursday Nights from 7PM to 1AM on the following dates:

Computer Reboot Loop Issue

At approximately 10 am, an error message popped up on hundreds of HSPH computers warning users that they had a virus and their computer would shut down in 1 minute. Their computer was then stuck in a reboot cycle.

This was not actually a computer virus outbreak, but rather a faulty data update from our security vendor McAfee.  This issue was global and not isolated to HSPH.  There are reports of other universities, government agencies, and businesses experiencing similar issues (see below for news articles).

Timeline:

  • Issues surfaced at approximately 10 am after computers at HSPH started to receive the automatic update from McAfee (DAT 5958).
  • HSPH IT staff worked closely with McAfee for several hours including hosting a Webex session from McAfee to an “infected” machine at HSPH. 
  • McAfee released an updated data file at approximately 1 pm.
  • HSPH IT staff tested both a pushed deployment fix using Novell and a manual fix for other users.
  • At 2 pm, HSPH Helpdesk sent email to community with instructions for Novell users to update the data file.
  • At 2:30 pm, HSPH Helpdesk staff started going floor to floor to update computers in need of manual updates.

Other Notes:

  • Computer laboratory machines and classroom machines were not impacted.  Neither students working in computer laboratories nor courses were affected.
  • Mac computers were not impacted.
  • Not all users at HSPH were impacted.

Update procedure if on Novell network:

  1. REBOOT your computer
  2. LOGIN to Novell
  3. Wait for the computer to RESTART itself (approximately 1-2 minutes)
  4. Your computer should then be updated with the new data file and you can login.

Update procedure if you do not login into Novell:

  • Contact the Helpdesk at 432-HELP, helpdesk@hsph.harvard.edu.  It will most likely require a technician visit to manually install the new datafiles.

HSPH Website Migration Completed

On Monday, December 21st at 6pm the migration of the main HSPH Website was completed. Launching capabilities have been restored in the HSPH Publisher and publishing updates will appear immediately as before with no delay.

Benefits:

  • New server is faster, more flexible, and has a larger storage capacity
  • New server is virtualized and part of HSPH’s disaster recovery plan.  In
    case of an emergency, this will enable IT to fully restore the main web
    server from our offsite DR location in a matter of hours.

A special thanks goes out to the HSPH Server Team, HSPH Web Team, and University
Information Systems
for making this switch possible.
If you have any questions or concerns regarding this migration please email the HSPH Web Team at webteam@hsph.harvard.edu.

Web Server Move on Monday

On Monday, December 21 beginning at 3 pm, there will be a delay in publishing new content to the HSPH website (http://www.hsph.harvard.edu) for several hours.   The Department of Information Technology is moving the website to new hardware and making necessary network changes in coordination with University Information Systems.

Community Impact:

  • The HSPH website will remain accessible for all users.  Internal and external website visitors should not see any impact.
  • All web applications will be fully accessible. 
  • The HSPH Publisher (CMS) will not allow publishing for 2-3 hours.  Any content updated in the HSPH Publisher will be delayed for several hours and will require a relaunch once our work has been completed.
  • Users with FTP accounts will likewise experience a delay in their content being updated.

Benefits:

  • New server is faster, more flexible, and has a larger storage capacity
  • New server is virtualized and part of HSPH’s disaster recovery plan.  In case of an emergency, this will enable IT to fully restore the main web server from our offsite DR location in a matter of hours.
