>Redis is really reliable (in my experience at least)
Redis has been demonstrated[0][1] to lose data under network partitions. This is particularly concerning when discussing the type of partial failure that GitHub reported.
Not sure how your comment refutes the contention of reliability. Seems to me to be more a condemnation of failures that do happen (which is of course worthy of concern, but irrelevant in a conversation about stability).
I am using "reliability" in the sense of RAS[0]. An HA datastore which erroneously ACK's writes has lowered reliability, as there are known cases where it gives incorrect outputs.
