Web Server Upgrade

| No Comments

ITSS is replacing our existing web server (www.d.umn.edu) with newer hardware and software. A Web Server Upgrade guide has been prepared that will help you prepare for the changes that will happen on Monday, October 31, at 6AM. If your web sites do not use CGI (PHP, Perl, C, C++, etc) or data base systems, it is very likely no changes will need to be made to your web sites. If you do use CGI components or use data bases then it's important that you test ahead of time and be prepared to update your web pages on October 31.

ITSS staff have discussed and decided against a test run before the October 31 deadline. Here are some reasons why:

  • The ITSS web server has more than our main web server on it, web1.d hosts many other "virtual" web servers. These servers would be affected twice, both when moving to a test system and also moving back to the base system.
  • There are DNS (name service) issues, as DNS servers have differing cache lag times. Customers might see the new test server or fail attempting to see the base one.
  • Web pages using data storage devices might have conversion issues after returning to the base system.

ITSS recommends focusing on the October 31 conversion rather than possible web, DNS or data base related issues.

Everyone can do some testing (first pages for sure) at either of the following URLs

Remember, if you have web pages that utilize CGI it is very important that you test them before October 31, 2011.
