Sure, any new piece of infrastructure we add has the possibility for reducing reliability. We only introduce things we think we can support, and that add value for the company. YMMV. We also have less than 15 minute incident engagement times, and don't let important pages slide through dinner. It's totally standard ops stuff: if one of the servers is down, we'll replace it when we get around to it. If they're all down, pages are going off.
