Administration Building to Get its Own Network Sept. 30

Stony Brook University's Administration Building

In order to improve network connectivity in the Administration Building, the Division of Information Technology (DoIT) will be creating a separate, isolated network exclusively for Internet traffic for the Admin Building, which will mitigate outages and service disruptions caused by problems in other buildings connected to the main campus network. It will also provide an extra layer of security and protection. The cutover will happen on Tuesday, Sept. 30, 2014, at 4 a.m.  There should be no service disruption and no other buildings should be affected by the cutover.

Client Support staff members will be on site in the Administration Building the morning of Sept. 30 to monitor the situation. If you notice an inability for certain devices (computers, cameras, printers) to access the new network, or if you have trouble accessing certain applications in the days, weeks, or months following the cutover, please call 2-9800 to report issues. Thank you.

Internet Connectivity Restored

Update:  Aug. 13, 12:32 p.m. – WolfieNet-Guest Wi-Fi Access Restored

WolfieNet-Guest is now operational after one of Stony Brook’s internet service providers was brought back online.


Update:  Aug. 13, 11:30 a.m. – All Services Restored Except for WolfieNet-Guest

Stony Brook guests are currently unable to connect to the WolfieNet-Guest Wi-Fi network as part of a lingering effect of yesterday’s wide-spread Internet connectivity issues. DoIT’s Data Network Services team is actively working to bring this service back up.

Yesterday, Stony Brook University users may have noticed inconsistencies while browsing certain websites as well as six 2-3 minute outages while DoIT’s networking team worked with SB’s internet service providers (IPS’s) to restore services by switching over to SB’s secondary and tertiary network providers.

The initial problem was caused when a flood of new routes were advertised on the Internet. These new routes brought the number of total routes over 512k which is the routing table limit for many Internet routers, creating problems for most of the major ISP’s in North America. Once Stony Brook realized there were problems with its primary ISP, it switched over to its secondary ISP and when that did not remediate the problem, it then had to turn to its tertiary ISP. Switching to its tertiary ISP resolved most of the problems that end users were experiencing.

The remaining browsing problems people were still experiencing were triggered by the initial routing advertisement which cascaded down to the campus border router bringing its table beyond capacity and causing it to act erratically in routing traffic to the Internet. Once Stony Brook rebooted its hardware at 8:15 p.m. all traffic then began routing as expected.

Here is a further description of the root cause of yesterday’s issues and its impact across the Internet:


Update:  Aug. 12, 8:40 p.m. – All Services Restored

A flood of new networking routes overwhelmed internet service provider (ISP) routers, which caused multiple service disruptions throughout the day on Aug. 12. Stony Brook’s Data Network Services team, working with SB’s internet service providers, have since resolved all issues. All systems (DoIT websites, including the IT System Status page, SOLAR, Blackboard, as well as other Stony Brook sites) should now be fully accessible from both on and off campus.


Update: Aug. 12, 8:12 p.m. – Network Outage beginning 8:15 p.m. 

Due to severe internet traffic issues today that are beyond our control, we are forced to take down our primary router for a period of 10-15 minutes starting at 8:15pm. This means people outside of the Stony Brook campus network will not be able to reach our websites. It also means people inside the Stony Brook network will not be able to access websites off campus. Users on campus should be able to reach most Stony Brook websites.


Stony Brook University is currently experiencing network-based Internet access issues for both on and off campus users. Users have reported they have inconsistent access to DoIT web sites (including IT System Status), SOLAR, Blackboard, as well as other Stony Brook sites.

We are working closely with our internet service providers to resolve the problem. Status updates will be provided on the IT Status site for those who can access it ( and at the SBUDoIT Twitter feed (

Power Issues in the ECC May Affect Network Connectivity

As a result of the power outage that occurred on campus on May 29, the ECC Building was adversely affected and continues to experience electrical power issues. Last night, building generators failed and as a result, network connectivity was lost from 7 p.m. until approximately 8:27 p.m.

DoIT continues to work with Campus Operations and Maintenance to investigate and solve these problems, but in the meantime, please be advised that network connectivity may continue to be affected periodically.

We will provide an update when there is more information to share. Thank you for your patience.

DoIT Calls for NetID Password Changes in Response to Heartbleed Bug

Stony Brook University's Heartbleed NetID Password Change Poster

Help us spread the word by downloading, printing, and hanging up the poster in your area.

CIO Cole Camplese issued the following campus announcement on April 15, urging everyone to change their NetID passwords as a result of the Heartbleed Bug …

To the Campus Community:

Good afternoon. Due to our current understanding of the Heartbleed Bug that has impacted the majority of the Internet, I wanted to provide you with a brief update on our progress and immediate next steps. We have no evidence that any Stony Brook University system or user credentials have been exploited by the Heartbleed Bug. However, we feel in order to protect your data and the institution’s data and out of an abundance of caution, you should change your Stony Brook NetID password.

To change your Stony Brook NetID password, please follow these directions carefully:

Security Alert: OpenSSL “Heartbleed” Bug

heartbleed bug icon

Several media outlets reported a serious vulnerability in OpenSSL 1.0.1 through 1.0.1f (inclusive) called “The Heartbleed Bug,” on April 7, 2014. This represents a serious Web security flaw that may compromise privacy. Please see the following news articles and websites which describe the issue in greater detail:

If you run a Web server with SSL (specifically OpenSSL 1.0.1 through 1.0.1f), it is  recommended that you patch the software immediately and upgrade to OpenSSL 1.0.1g. If you’re stuck with a previous version of OpenSSL for some reason, you can block the vulnerability by re-compiling it using the OPENSSL_NO_HEARTBEATS flag. OpenSSL 1.0.2 will have the bug fixed in the upcoming 1.0.2-beta2 release. If you do not know what version of SSL you are running, go to and enter your site’s URL to find out if the site is vulnerable.

Additionally, if you have contracted with any vendors who use SSL, please contact them immediately to find out if they have applied the current patches and to find out what other steps may be required.

One of the side effects of this vulnerability is that the server private key may be compromised and there may be no trace of it. In this case, after patching, please generate new keypairs and request a new certificate. DoIT will provide a new Comodo/Incommon certificate to its Stony Brook IT Partners at no cost if they just email the CSR to

DoIT is actively monitoring the situation here at Stony Brook and has contacted its vendors about any vendor-supplied software.

Stony Brook’s SOLAR, PeopleSoft, Blackboard, and Google Apps for Education systems are not affected by this vulnerability. Other systems accessed with your Stony Brook NetID and NetID password are not affected.

Individual users may want to consider changing the passwords on all their sensitive Internet accounts, such as banking accounts, private email accounts, and any accounts created for online shopping with the use of credit card information. However, the New York Times Bits blog suggests waiting a day or two to allow time for websites to get patched.

DoIT has created a public Yammer group to provide the campus community with updates as this situation unfolds and develops. Please post your questions and comments to the Heartbleed Bug Info Yammer group.
