What an NBN® eSLA (fault service level) is, the difference between Standard, Enhanced-12 and Enhanced-4, which plans include them and what happens when you change plan.

An eSLA (fault service level) is how fast NBN® works on a fault with your connection. It does not change your speed.

#2 The levels



StandardThe usual NBN® repair times.
Enhanced-12 (24/7)Worked on around the clock, aiming for a fix within 12 hours.
Enhanced-4 (24/7)Worked on around the clock, aiming for a fix within 4 hours.



The number is how many hours NBN® aims to take to fix a fault. A level that says business hours counts business hours only.




#2 Which plans include what



CrazyNBN plansStandard fault repair.
SuperCrazy NBN® plansFaster fault repair included at no extra cost. On some you choose between Enhanced-4 and Enhanced-12 when you order; both are included in the plan price.
Fixed WirelessStandard.



Each plan on Available Plans shows the level it comes with. Fault repair is never sold as an extra.




Changing plan? When you change to a plan with a different level, the plan change goes ahead as normal. Our team then updates the level with NBN®, which takes 1 to 2 business days. Until then the tile says the new level is being added.
