docs/data/reusables/release-notes/2024-01-haproxy-upgrade-causing-increased-errors.md

The upgrade of HAProxy to version 2.8.4 (to address scenarios that could lead to denial of service) is causing elevated error rates when HAProxy is upgraded as part of a hotpatch upgrade to a {% data variables.product.prodname_ghe_server %} instance. These elevated error rates should resolve within 5 minutes of the hotpatch being applied.

Please note, when performing a hotpatch upgrade to {% ifversion ghes = 3.8 %} {% data variables.product.prodname_ghe_server %} version 3.8.12 or higher {% elsif ghes = 3.9 %} {% data variables.product.prodname_ghe_server %} version 3.9.7 or higher {% elsif ghes = 3.10 %} {% data variables.product.prodname_ghe_server %} version 3.10.4 or higher {% elsif ghes = 3.11 %} {% data variables.product.prodname_ghe_server %} version 3.11.1 or higher {% endif %} you will encounter this known issue only if you are hotpatching from {% ifversion ghes = 3.8 %} {% data variables.product.prodname_ghe_server %} version 3.8.11 or lower {% elsif ghes = 3.9 %} {% data variables.product.prodname_ghe_server %} version 3.9.6 or lower {% elsif ghes = 3.10 %} {% data variables.product.prodname_ghe_server %} version 3.10.3 or lower {% elsif ghes = 3.11 %} {% data variables.product.prodname_ghe_server %} version 3.11.0{% endif %}.
