Q: How good are the network availability service level agreements (SLAs)?
Most of the service providers with nation-wide backbones guarantee the network will be available at least 99.6 percent of the time. That translates into a maximum outage time of about 6 .5 minutes a day before the refund or credits kick in. Some offer higher availability with refunds or credits kicking in for outages of 3 minutes per day or longer.
