Services on the my.ryerson portal were restarted this morning between 10:17 AM and 10:22 AM to implement a fix related to the problems we experienced yesterday evening. The cause of the problem was traced to the Blackboard My Announcements portlet code, which under some circumstances was going into a infinite loop.
We apologize for the service disruption.

Computing and Communications Services
Some users of the Campus Wi-Fi network are experiencing poor performance and connection problems due to the large number of people connecting to Wi-Fi access points in certain locations. The areas exhibiting the greatest congestion are:
1. Library Building
– LIB-72 Lecture Hall
– 2nd floor “Commons” area
– 4th Flr north west corner
– 6th Flr south west corner
– 7th Flr south side of building
– 8th Flr south east corner
– 9th Flr south east corner
2. George Vari Engineering and Computing Centre(ENG)
– Lower Ground
– ENG-201 Area
3. Kerr Hall East (KHE)
– Near KHE-119
– Near KHE-124
– Near KHS-247
– Near Lecture Hall KHE-225
– Near Lecture Halls KHE-322 and 332
The problem is partly the result of the steady increase in the usage of smart phones and iPads on campus. At times the number of smart phones and tablets connected to Wi-Fi access points represent 50% of the total number of Wi-Fi connections.
Computing and Communications Services has an ongoing program in place to increase the number of access points, which will reduce the access point-to-user ratio across campus and improve performance. The highest priority is being given to the areas listed above.
We apologize for the lack of coverage in these areas.

Update February 17, 2012:
Over the weekend starting February 25 CCS will begin work on adding 18 new Wi-Fi access points in the Library building. If all goes well, the new Wi-Fi access points will be enabled on Monday Feb 27 and should relieve some of the Wi-Fi congestion in the Library.
The following list is where we plan to add new library access points:
5 – 1st floor
3 – 2nd floor
1 – 4th floor NW
3 – 5th floor
2 – 6th floor
1 – 7th floor
1 – 8th floor
1 – 9th floor
1 – 10th floor
We are also working through our options to add access points in the ENG building. Once we have scheduled work in ENG we will post more information about Wi-Fi upgrades here.
Update February 28, 2012:
On Monday Feb. 27, 14 new access points came online in the library. The remaining four should be online today.
Update March 6, 2012:
Over the weekend starting Saturday March 10, CCS will begin installing another 19 access points in the George Vari Engineering and Computing Centre (ENG). We will add 9 on the 1st floor and 10 on the LG level. In the summer we will add more access points the 19 we add this weekend should help reduce congestion.
Update March 12, 2012:
Unfortunately, while new cables were installed last weekend in ENG, the installation work was not completed. The new access points will not be available until some time after Wednesday.
Update March 29, 2012:

101,102, 103, 105, 106, 124, 132, 136, 157 LG4-1, LG4-2, LG13, LG14-1, LG14-2, LG21, LG23, LG24, LG26
We also added 16 more access points in Kerr Hall and replaced 2 defective APs. Locations:
3 APs in KHE-321C, 3 APs in KHE-321A, 4 APs in KHE-221, 3 APs in KHW-371, 1 AP outside KHN-111, 1 AP in Rye-O-Mat, 1 AP in KHS-45A, swapped out non functioning units in KHN-202 and KHN-3rd NE corner.
We also added 6 APs in Theatre School, outside the following rooms:
