I don't know if statuspage.io is similar to what you're doing, but their blog documents much of how they got profitable. Makes for interesting reading.
A little different: Services like statuspage.io, Runstatus, Cachet, Status.io, etc. all offer status pages. StatusGator aggregates all the status pages you care about into one status page for your own reference and also sends you alerts to email, Slack, etc, when those pages change.
I love the idea of blogging about growth and profitability. Seems like that could be a good marketing channel, in addition to being very educational.
