If you have over 11 hours of complete outage (nothing works) within a quarter they will be in violation of their SLA. Which makes you eligible for a small refund. If you jump through enough hoops, they will refund you one month's fees (calculated) for that quarter. I've done it and received a credit, but it was an obstacle course. Including submitting written request within 5 days of the end of the quarter, and getting them to confirm receipt.
It has to be a COMPLETE blackout (like today's issues) and you need to document all of the outages, and have their engineering team "agree" that they were indeed in breach of the NetSuite Service Level Agreement. It's a bunch of work, but it is possible to get a credit..... 1/12th your annual fees (max of one credit per year). May the odds forever be in your favor, lol.
