Thanks for your love. Regarding Iris Couch, I am biased; but I myself have
nothing but love for the people at Cloudant, too. Of course, ultimately,
you don't need people, you need the stuff they make and do (i.e. CouchDB

You are right that we have had issues lately. We've always had random
failures; but this is the first time things have gotten bad enough that
general users felt prolonged slowness or unavailability.

Long story short: these issues are behind us and we are back to our
well-known quality of service.

I thought our failure would be a boring story, but maybe I'll tell it

The big problem was that we failed to support people, not that we failed to
run software. Do you know how lots of stuff runs just fine from 0% to about
90% or 95% capacity, then it collapses horribly (e.g. memory, filesystems,
disk i/o)? We experienced a similar collapse with customer support.

The past two weeks, due to vacations and traveling engineers, we were doing
less regular maintenance than usual. Then, also randomly, a few machines
crashed badly. As a sysadmin I like CouchDB, because only safe operations
are allowed. (For example, CouchDB has no JOINs, therefore every read
operation is guaranteed to complete in logarithmic time.) That is usually
the situation; however there is still the occasional memory leak or out of
control process or whatever. Anyway, we exhausted memory on several
machines which crashed many people's couches.

That's fine; but the real collapse happened when everybody began to inquire
about their server. Fixing stuff over SSH is quick, but supporting people
takes much more time. When we saw the support volume spike, I decided to
enter triage mode: make a priority list of technical and personal
obligations and work from the top down.

All software has real-time constraints. In fact, all human activity has
real-time constraints. Right? Right? Hello? Hello! Can you hear me? After a
certain time, if something is not done, it may as well never be done. That
is how I approached our support load.

I have learned from many trusted advisors (Hi, Jan and Noah and everyone!)
that "support load" is a terrible phrase. CPU load is CPU load; but
"support load" is people. So, I have learned my lesson, and we are now
working through the entire backlog. Some people emailed to tell us
nevermind, they had moved to Cloudant. I think they wanted to twist the
knife a bit, to blow off steam. Okay, but that put them near the bottom of
our priority list (they are no longer using the service; outstanding issues
are moot). However they are still people. We will be emailing even them, to
say the issue has been resolved. If you ask a question, I should respond,
otherwise it's rude.
