Status page is for outages & maintenance only. Since this is not applicable to all accounts and should only last at most a few days we have decided not to post to our status page.
Haha that's a great idea for a "dirty tricks" campaign against a competitor. Every time they have an outage, a greenbean HN user starts posting less and less plausible excuses with the aim of pissing everyone off. Eventually the real CEO has to get on and say, "We don't know who this is but please ignore them but no I don't want to say anything about our outage." Repeat for added lulz...
What's extra ironic is that Sendgrid employees were gloating on HN and posting inaccurate information about competitors when the Mandrill TOS change was announced. I think they really need an enforced social media policy.
Overall, I think Sendgrid does a fine job and it's unlikely this mistake will be repeated. These gaffes don't represent the majority of the company.
For many users email is a business critical function, the reason we pay other people to do deal with it is because it's a tricky business critical function.
If using yourselves is going to result in problems like this then I fail to see what we'd be paying for.
