    [Update] Connected backup service is up and running and technicians are continually monitoring the situation.  We are in the process also of moving our customers to a new connected backup server which will help alleviate some of the issues we have experienced in the past weeks 

    [Original Alert]

    Begining on about 9/19/2014, Connected PC Backup began missing most client backup schedules. CUIT administrators have been notified and are currently working to resolve the issue.

  • UNIX Hosting/Application Service
    09/26/2014 - 06:29pm to TBD
    A new computer vulnerability has surfaced this week called the "Shellshock bug".  This bug is in software on many UNIX computers
     (Linux, Solaris, Mac OSX, AIX, etc.) and in tiny computers inside consumer devices such as routers and web cams. 
    As of Thursday, researchers could see that hackers have already launched attacks exploiting this bug, as complete patches are still not available.

    Columbia University has not yet seen any hacking activity related to this vulnerability, but we are taking precautions by updating our servers as patches become available and will continue through the weekend.  We will work toward making our upgrades unnoticeable, however, given the large number of servers that we manage, there is a possibility that some programs may become unavailable.  If, during our upgrade you notice any programs performing or behaving irregularly, please contact the CUIT Service Desk at 4-1919.
