Many schools are currently experiencing problems with accessing web pages. A message indicating that the web filtering service is unavailable is shown instead of the web page requested. This is not affecting all schools and in those schools that are affected it seems that the web service is not always denied to all machines.
This is being investigated urgently by Updata as a Priority 1 incident but as yet we have no indication as to when it will be fixed.
We apologise for the extreme disruption that is is causing as schools return from half-term. We will keep you informed of progress to resolution through these pages.
Update: 9:20 am
Updata have reported that they have discovered that proxy 3 in data-centre LD5 had become unavailable and that they believe this has been the cause of the web service issue this morning. This proxy has now been removed from service and they believe that this has fixed the problem. Please call the Service Desk if you are still experiencing a problem. We will provide a fuller explanation as soon as we have it.
