I found that IPv6-only connected users can’t download LibreOffice, because nearest mirror don’t answer via IPv6. Please, add separate monitoring for all systems of LibreOffice website. IPv4 and IPv6 are two different Internet’s and needs separate monitoring of availability.
It will be very nice if all mirrors will answer via dualstack (IPv4+IPv6), but if they can’t - please don’t link to the IPv4-only mirror for IPv6 users and some with links to the IPv6-only for IPv4 users.
