My site starts sucking again at random, with some simple ajax queries taking 200ms most of the time but randomly spiking up to 5 seconds. In the past, I have determined this to be cloudflare screwing up (you will never find any admission of this from cloudflare). I tried to log in to turn off this garbage (possibly for good) and could not log in. Sometimes it shows the login form but then shows a red api error banner at the bottom.
Good thing all systems are operational.
