17 October: Google announces new look and feel for Google Calendars

3 hours 32 min ago
Don't be surprised to find your Google Calendars looking different. Google have done some work to improve the user experience, particularly on mobile devices. See: [https://www.blog.google/products/g-suite/time-refresh-introducing-new-look-and-features-google-calendar-web/](https://www.blog.google/products/g-suite/time-refresh-introducing-new-look-and-features-google-calendar-web/)

Wireless Service: Resumption of Phase One of the 2N Resiliency Project

Tue, 10/17/2017 - 15:02
After a short pause to fix a technical obstacle we are happy to announce that we are able to restart the 2N controller resiliency project to the University Wireless Service. As a reminder, the wireless controllers coordinate the activity of all 5000 University wireless access points spread throughout the City. Presently we have an N+1 resiliency configuration (this is a master controller, a standby master controller and a single back up controller for the six local controllers). We are going to migrate this to a full 2N configuration over the coming weeks which means all seven central controllers will be fully replicated with another seven controllers in a separate resilient site. We plan to do this work in several phases, and whilst the first phase will achieve 2N resiliency, we also plan to add to the level of resiliency in subsequent phases. Unfortunately, this entails several outages, some of which are more disruptive to service than others. Lastly, as part of this reconfiguration work we are introducing changes to the way the underlying network arrangements for the Wireless system function in anticipation of adopting the next release of the Aruba Operating System (AOS 8). Adopting this OS will require a software rebuild of the wireless system. As such this will be a separate major project which will be announced nearer the time. Phase One The first of the 2N migration will be the setup of full replication in two disparate sites on the West Cambridge Site. The primary site will initially be in the Roger Needham Building Data Centre and the secondary site will be in the West Cambridge Data Centre (WCDC). Both these sites have backup networking and power resilience. To migrate to this configuration will require five out of hours outages, which are detailed below. An additional outage will also be announced at a later date. Phase Two In phase two of the reconfiguration we plan to move the wireless controller infrastructure to the distribution layer of the Cambridge University Data Network (CUDN). This will achieve geographic diversity but will also gain a big increase in network efficiency. Proximity to the centre of the CUDN will mean that Wi-Fi traffic can enter and exit the CUDN more efficiently. This phase will also enable us to explore load balancing arrangements for the controllers and due to the growing scale of the Service we also plan to place the controllers on their own router infrastructure. The timescale for this stage has yet to be determined. Phase Three In the last phase of this reconfiguration work, we plan to introduce resiliency for the supporting infrastructure that the Wireless Service relies upon. A timescale for this stage is yet to be determined. Phase One Outages Tuesday 24th October 08.00 – 09.00 (Service liable to short interruptions during this period). Tuesday 31st October 08.00 – 09.00 (Service liable to short interruptions during this period). Thursday 2nd November 07.00 – 09.00 (Service liable to longer periods of disruption during this period). Tuesday 7th November 08.00 – 09.00 (Service liable to short interruptions during this period). Tuesday 14th November 08.00 – 09.00 (Service liable to short interruptions during this period). During these outages we are conducting significant system changes, as such please expect some periods of no service during this time and the possibility of more than one outage. To clarify, this means that devices may be unable to connect to, or pass traffic via, the University Wireless Service. This will affect connectivity to the UniOfCam guest SSID, eduroam and all locally bridged SSIDs.

Wi-Fi WPA2 Security Vulnerability

Mon, 10/16/2017 - 15:37
As per recent news articles we would like to bring to your attention the announced security vulnerability in Wireless Protected Access II protocol (WPA2), which is commonly used in securing the connection to wireless (Wi-Fi) networks both in the office and home environment. This is an important announcement because all Wi-Fi network and client devices are potentially vulnerable to this security flaw. The University Wireless Service runs a central controlled deployment of Aruba access points. Aruba Networks have already released a patch for this vulnerability and the University Wireless Team will be installing this between 08.00 and 09.00 on 17 October 2017, as previously announced. Those institutions who run their own infrastructure are advised to take steps to update their own devices as soon as possible. It is important to be aware that this vulnerability also needs to be patched on client devices (e.g. PCs, laptops, smartphones, iPads etc) and most major vendors should be releasing updates for these. We strongly advise that users update their software as soon as possible. We also recommend that devices that no longer receive security updates should not be attached to Wi-Fi networks, including the University Wireless Service (via eduroam or UniOfCam).

6 October: Changes to the Exchange Online Global Address List

Fri, 10/06/2017 - 11:58
Yesterday we rolled out proper names into the Blue Active Directory (AD) and, hence, the Exchange Online Global Address List (GAL). Unfortunately we neglected the case when people's preferred name was not the same as their formal name (as recorded by the HR system). We received user feedback pointing this out and corrected our process mid-day. Note that none of this affects students (whose data comes from CamSIS) and staff not managed via CHRIS.
