I see you are unfamiliar with status page-ese. “Degraded performance” is a term which means some form of “the entire datacenter is probably on fire”.
Although I only post here personally, I work for Let’s Encrypt.
Let them know that they're having an outage. If their monitors aren't telling them so, they might need to host them off-site.
Let's Encrypt is operating normally. If you're having trouble, please post the details on the community forum so that folks can help you out. There is external monitoring in place.
Thanks you for your work!
It would be better to say this upfront. I am not blaming you in any way but this would prevent responses such as the parent's (hopefully).
I thought it meant "electricity has ceased to be a physical phenomenon in the general vicinity of our servers"
A common confusion; this interpretation only applies to OVH.
