There appears to be a problem with UUNet's DNS server. We have reported the problem to them and they are investigating the problem. This will result in being temporarily unable to resolve any internet addresses. ArgoNet are currently experiencing mail difficulties, as well as problems with ArgoNet customers web sites, which started at approximately 9pm this evening.
Engineers are currently on site at London and working to resolve the problem as a matter of urgency.
A further post will be made here when more details are available. The fault was caused by a disk array failure on our main server. This has now been fixed and the service returned to normal. Please note that email transport may be delayed until approximately 6am as the backlog of mail is cleared. We would like to sincerely apologise for the loss of service this evening.
