Outages happen to everyone, including I'm sure Discord, and what matters most to me is transparency during and after the incident and that both individual and corporate values include incremental improvement - not making the same mistake twice.
I'm perpetually frustrated by HN comments which take a tack of either pointing out (with your benefit of hindsight) things the commenter feels were incorrect, professing they could do better, or the strong advocacy for abandoning ship even with companies who have a provably pretty decent uptime record.
Unfortunately I cannot sympathize with a company which it's valuation is $2.8 billon, and cannot handle staying up or a large userbase.
