False. Just calculate what those five mins mean. And remember in percents so you have to divide by an extra 100

Five-nines or 99.999% availability means 5 minutes, 15 seconds or less of downtime in a year. Or, if you are really ambitious, shoot for six nines or 99.9999% availability, which allows 32 seconds or less downtime per year.
