Does ADSL come with an SLA?
Most providers do not offer service level agreements with broadband services. This means that if there is a fault, then there are no guarantees of a fix time. Even where there is an SLA, the onus is usually on the customer to prove the breach of agreement and to claim the compensation, which is usually disproportionately small compared to the losses incurred in a network outage. Opal recommends broadband customers employ a back up service using ISDN with automatic fail over between the two circuits, particularly in business-critical applications or for VPNs.
