Investigating
We found some problems with our last update to haproxy 2.2 and TLS 1.2 earlier this week, and rolled back the previous release (https://0-status-crossref-org.libus.csd.mu.edu/incidents/ftwpm7ztg9n3). We will be undergoing unplanned maintenance today, Wednesday, 3 February, from 2300 to 0100 (4 February) UTC to update to haproxy 2.2 and TLS 1.2. Users may experience intermittent outages during this time. As a reminder, this update will strengthen the security of our web servers, and will again result in disabling TLS versions 1.0 and 1.1.
