OIT Service Updates

Maintenance to one set of OIT network load balancers is scheduled for Saturday July 4 at 6am. Maintenance should be complete by 6:30am. While we anticipate no interruption in service as a result of this work, brief interruptions to load balanced services (email, web, etc.) cannot be entirely ruled out. OIT staff will be monitoring the situation closely and will be ready to quickly respond should such events occur.

On Friday, July 3 06:00 - 09:00 EDT, OIT Network Services will be performing preventative maintenance on core data and voice infrastructure. There are no outages expected during this time. If you have any questions or concerns about this change, please contact the OIT Help Desk at: 684-2200, help@oit.duke.edu, or at the website: https://www.dunk.duke.edu/secure/submit/index.html

In our efforts to improve the availability of the DHCP service provided by OIT Systems Operations, we will be migrating the NSOE, BioSci, and Data Center networks to a newer pair of redundant, fail-over capable DHCP servers on Thursday, 07/02/2009, starting at 06:00AM and lasting no later than 07:00AM. During the migration, all dhcp servers will remain operative and therefore dynamic dhcp users on NSOE and Bio Sci should see no interruption in their ability to receive an ip address. Because of the static nature of the Data Center networks, and the use, in most cases, of dhcp only upon initial operating system install, there should be no impact to services on those networks. If you have any questions or concerns about this change, please contact the OIT Help Desk at: 684-2200, help@oit.duke.edu, or at the website: " https://www.dunk.duke.edu/secure/submit/index.html "

OIT, in coordination with Verizon, will be performing network maintenance tonight on the links providing connectivity to some remote sites.

[Update - July 1] During our upgrade of ViewsFlash today, we uncovered a problem that was previously undetected in several rounds of testing. In a nutshell, the problem is that surveys that had Webauth authentication enabled in the old version (version 3) -- which would have allowed you to restrict access to users with NetIDs--- are not accessible as expected in the new version. We have identified a solution to this problem, but it will take us some additional time to make manual changes to affected surveys in your polling places so they will work as expected. For this reason, we will be extending the ViewsFlash outage until 2 p.m. tomorrow (Thursday, July 2nd) afternoon. We deeply apologize for any disruption this may cause. [June 30] The ViewsFlash survey tool will be upgraded from version 3 to version 6 beginning at 6 a.m. on Wednesday, July 1. The upgrade will take approximately 24 hours and ViewsFlash will be unavailable during this time (i.e. you will not be able to access surveys or data related to any surveys in either version).

OIT staff are continuing work on the network load balancer infrastructure to improve availability and performance. As part of these efforts we are working to implement a software code update on our load balancers. Our vendor has suggested this upgrade to mitigate and resolve a bug that is believed to have caused an outage period last Friday morning. This code upgrade is scheduled for implementation this Friday, July 3 at 6am. Maintenance should be complete by 6:30am. UPDATE: Maintenance is continuing as of 7:45am. While we anticipate no interruption in service as a result of this work, some aspects of the maintenance will create situations similar to those that have created previous load balancer service interruptions, so a brief interruption to load balanced services (email, web, etc.) cannot be entirely ruled out. OIT staff will be monitoring the situation closely and will be ready to quickly respond should such events occur.

We are currently experiencing connectivity issues with remote sites. We are working with our carrier, Verizon to fix the problem.

The dCal calendaring service (via the Oracle Calendar client and schedule.duke.edu) is unavailable due to emergency maintenance. This issue has been RESOLVED.

The Pinnacle system is currently unavailable. Students will be unable to change telecom services or pay bills via www.duke.edu/online

The dCal calendar service, including desktop client, web client, mobile device synchronication and Oracle Calendar for Outlook, is currently unavailable. OIT is currently working to restore the service. We currently do not have an ETA for resolution.

OIT is currently experiencing an issue with mail delivery. Staff are currently investigating the issue and will post updates when available. This has been RESOLVED. Mail sent between the periods of 9:30am and 11am may have resulted in bounce back messages. These emails will need to be resent. This did not impact third level domains such as @mc.duke.edu.

SISS will be undergoing maintenance from 6:00 pm until 9:00 pm. Users may be unable to access ACES, Peoplesoft, STORM during this maintenance.

The NotifyLink Service will be unavailable. We are upgrading server software to allow for an improved web interface, improved security, and a variety of enhanced capabilities for specific device types including improved battery life management, improved memory use optimization, and improved attachment handling and WiFi support for BlackBerrys. Some new BlackBerry client features will require updating the NotifyLink client on the device. Users will not receive mail or PIM updates (calendar, contacts, tasks) on their mobile devices via NotifyLink during this outage. After the upgrade, mail messages and PIM updates that are intended to reach the mobile device will be delivered. If you experience any problems after the upgrade, please contact the OIT Service Desk at 684-2200.

Duke Pass (dukepass.duke.edu) is currently unavailable. There is no ETA for resolution at this time.

The Remedy application is scheduled for a maintenance window on Saturday, June 20th, 9am - 10am. During this downtime, we will apply MS patches to the mid-tier environment which will render the following Remedy features unavailable during this timeframe - Remedy via web, Remedy Knowledge Mgmt tool (RKM), Firewatch Pager Re-assignment Page and Flashboards on the local client. The locally installed Remedy client will remain fully functional during the maintenance window.

OIT is currently correcting a technical issue with portions of the AFS service. Some users may see intermittent access issues with their data.

As an extension of the maintenance of DHCP servers, wireless users on Central Campus may experience issues gaining a valid IP. There is no ETR at this time.

OIT will be performing scheduled network maintenance in the North Building data centers between 10pm and midnight this Sunday, June 21, as part of ongoing work to improve the availability of campus server facilities. A brief network outage to affected servers will occur during the window; 1-2 minutes of interrupted connectivity is expected, although widespread service interruptions are not expected. Possibly affected servers include a number of production, test and development supported by Arts & Sciences, Biology, Chemistry, IGSP/Genomics, Public Policy, Student Affairs and TIP. Also possibly impacted are test, development and failover servers supporting services that include Blackboard, PeopleSoft/SISS, ImageNow, the Duke Event Calendar, Time & Attendance, Remedy, DukeMail, identity management services, Flash and Windows Media streaming media, Adobe Connect, SAP Kofax, Google search appliance, and ESSBASE.

In our efforts to improve the availability of the DHCP service provided by OIT Systems Operations, we will be migrating all Wireless networks to a newer pair of redundant, fail-over capable DHCP servers on Thursday, 06/18/2009, starting at 06:00AM and lasting no later than 07:00AM. Shortly after the servers start up, there may be a brief period of time (less than 10 minutes) where users trying to renew a lease may be unable to get a new ip address. If you have any questions or concerns about this change, please contact the OIT Service Desk at: 684-2200, help@oit.duke.edu, or at the website: https://www.dunk.duke.edu/secure/submit/index.html
