Firstly the article is about the use of C++ vs C in ZeroMQ (crossroads). Then the article is about systems having a high uptime and how C++ is not ideal for that.

Here is the quote:

> First, it's important to take into account that ZeroMQ was intended to be a piece of infrastructure with continuous uptime

So it is about uptime, that's the supposed goal of someone using ZeroMQ. C++ has undefined behavior and this, the author claims, can lead to more crashes and reduce uptime.

Then nirvana suggested that if uptime is needed, there is a better language and platform designed for it.
