I'd like to echo the sentiment that offering 100% uptime and 3x, 5x, 10x refunds is a dangerous decision and actually will not increase paid signups. I've been doing operations/DevOps for over a decade (in fact I just launched a consulting startup (https://elasticbyte.net https://elasticbyte.net) that helps companies manage their cloud infrastructure). 100% uptime is a red flag, ops professionals never guarantee 100%. You instead should offer standard 99.9% (44 mins a month) or 99.99% (4 min 30 sec) with standard SLA language.
