Update 15:20

The Jisc network has suffered a further loss of connectivity which is affecting the University’s internet access. For regular updates about this incident see Jisc’s Twitter: https://twitter.com/jiscmi/

More information to follow.


 

Original alert 11:28

Over the last hour or so you may have noticed a problem accessing the internet and some websites. This was due to a loss of service on the Janet network - the UK’s academic and research network the University connects to.

Janet have informed us they are seeing an improvement in connectivity and continue to monitor the situation closely.

If you’re still experiencing network problems, contact the IT Helpdesk.

The University of Essex will moderate comments and there will be a delay before any posts appear.

[Resolved] Problem with some IT services due to earlier University power issue

Filed under: Network, Wi-Fi, [Resolved], [Service Alert] — Dan Jolly @ 4:05 pm

Some IT services that rely on the network were temporarily unavailable this afternoon. This was due to an issue with the University’s main power supply which affected some of our core network equipment.

We believe the issue is now under control, however IT Services staff continue to monitor the situation closely.

Please restart your computer if you experience any residual problems.

More information to follow if any problems return.

The University of Essex will moderate comments and there will be a delay before any posts appear.

Service failure

Filed under: Email, Office 365, Telephone, Wi-Fi, [Resolved], [Service Alert] — Bret Giddings @ 3:18 am

[Update: 16:35]

The remaining issues (Telephony and Conference Wi-fi) have been resolved and a full service restored.


 

[Update: 15:10]

We have staff working on and off campus. Some equipment that failed as a result of the power difficulties overnight is being switched out and once this has been completed, we’ll review the still outstanding issues and provide an update.


 

[Update: 12:00]

ListenAgain was returned to service at 11:45


 

[Update: 11:15]

All services are assessed as operating normally with the exception of:

  • Telephony: Incoming calls to the University can’t be answered (all campuses). Outgoing calls unaffected. For incoming calls, the call ID may be visible and you should be able to ring back.
  • Conference Wi-Fi service (EventEssex) is unavailable.
  • ListenAgain is unavailable.
  • There is a secondary issue unrelated to datacentre power affecting access to email using Outlook and on some mobile clients. However, it should be possible to access email using Webmail at https://email.essex.ac.uk.

Next update: 15:00


 

[Update: 0430]

The problems affecting the home directories are mostly fixed. They should all be fully returned to service by 05:00


 

One of the University Datacentres lost power earlier today (18 Feb 2017), we believe as a result of a faulty environmental censor.

This resulted in the loss of many central IT facilities. Staff were onsite by 00:30 and most services were restored by 02:00. Some are still not available and will be worked on in due course.

Known issues at present are:

Moodle unavailable

Some home directories unavailable.

More information will be posted in due course.

The University of Essex will moderate comments and there will be a delay before any posts appear.

Ongoing problems affecting wifi and attendance monitoring devices

Filed under: Network, Wi-Fi, [Resolved], [Service Alert] — Bret Giddings @ 5:37 pm

Updated at 11:38

Following a reset of affected switches, we believe that all Wi-Fi access points and all attendance monitoring devices were fully operational by 2100 on Wednesday 19th October 2016.

The cause of the problem was the brief electrical power cuts early on 18th October. The power cuts caused some network devices to stop working properly. Unfortunately, the only fix was to power-cycle the affected devices which we we’re reluctant to do during work hours as this would have briefly affected network access for others in teaching or office spaces.


 

In addition to the issues affecting some SIP telephones (see http://blogs.essex.ac.uk/it/2016/10/service-alert-problem-with-sip-telephones/) there are also some known issues affecting some Wi-Fi access points and some of the attendance monitoring devices. The cause of the problems are related to the disruption to electrical power yesterday morning (18th October 2016). We hope to have resolved the majority of the issues by Thursday 20th October.

Where there are issues with Wi-Fi access points, there will be either no or slower than usual access to the Internet via eduroam.

The issues with the attendance monitoring devices mean that they are simply not functioning.

The University of Essex will moderate comments and there will be a delay before any posts appear.

Network issue Network Centre 27/07/16.

Filed under: Network, Wi-Fi, [Resolved], [Service Alert] — Network Manager @ 8:14 am

Further electrical testing in the Network Centre over night caused another network device to fail; thus network connectivity was lost on floors 1, 2 and 3 of the Network Centre until 9.05am this morning.  Apologies for any inconvenience.

As always PCs still exhibiting problems in the area should be rebooted before reporting any residual problems to the IT.Services Help Desk.

The University of Essex will moderate comments and there will be a delay before any posts appear.
