On Saturday 08/01/2020 there was an outage of the forum.
Most probably due to the delayed renewal of the certificate from letsencrypt.org:
What is the lifetime for Let’s Encrypt certificates? For how long are they valid?Our certificates are valid for 90 days. You can read about why here.There is no way to adjust this, there are no exceptions. We recommend automatically renewing your certificates every 60 days.
Following above link also tells:
We recommend that subscribers renew every sixty days. Once automated renewal tools are widely deployed and working well, we may consider even shorter lifetimes.
So, question: will we have to expect these outages now every 90 days?
Or are you planning a shorter renewal period or automation?
P.S.; thanks for taking care if this on a Saturday.
