The only thing SLAs do is tell you how much you will be compensated for downtime. If a fibre cut happens, you can end up with a 16 hour outage regardless of what the SLA guarantees. It all depends on the nature, location and extent of the damage. A couple of summers ago one of my wavelengths was down for more than 16 hours. 3 x 432 count cables had to be replaced through 3 manholes because a fibre seeking backhoe ignored the locates. Splicing high count cables takes a lot of time (even with ribbon fibre).
