There's a front page story every time google, apple or Amazon are down. I'm not sure telegram warrants the same publicity but it doesn't seem completely inappropriate.
Of course, I'm here commenting, so somehow I got enticed to click through to the comments, so who knows what that says about me...
The production server might have a 150 load, with swap 99% full and 0 disk space left right now, and you wouldn't get any alerts from the monitoring software, because telegram is down, and it has "never happened before".
