most outages only happens on a single az. which is not really hard to handle.
in over 1 year we had one outage on frankfurt. and that was just a small problem which a small reboot of our machines fixed the issues. oh and that happend automatically.
the problem is you need to know that failures could happen.
not only in the cloud but in the cloud these failures are more easily to handle since you could just create new boxes or use multi cloud envs.
