Like that Cloudflare outage from the other day? In any case, I'm sure there's good reason to believe that, as Rust gains popularity, there totally won't be proportionally more high profile issues in stuff made with it.
There's also Fil-C BTW, and in normal C++ there are GCC or Clang (I forget which) extensions for detecting threading issues, even good old Valgrind is under-appreciated and under-used. In general one wants to adopt best practices and be proactive, rather than relying on the language to solve all problems (of course).
