We'll be having a short maintenance tomorrow, 9 September 2025, starting around 9am PDT to apply a couple of configuration changes recommended by GitLab support following the slowdowns experienced last week. Whilst not yet a solution this should provide better performance for background jobs and potentially provide more information in the logs if/when the slowdowns start happening again. I expect the downtime to be brief, as in only a few minutes...

Include 'MDC' as an option for coinc_far

There is a potential bug when handling MDC events and calling to calculate the coincidence FAR to have it fail due to MDC not being an option. This could be called from gwcelery at https://git.ligo.org/emfollow/gwcelery/-/blob/aebb33f48c7d691761519ce86e3957f25df5da89/gwcelery/tasks/raven.py#L49, where this would fail due to the code https://git.ligo.org/lscsoft/raven/-/blob/8451723565744f145d5c0048d3774f9751e59792/ligo/raven/search.py#L273

A simple fix would to treat MDC events as standard GRB and modify the line https://git.ligo.org/lscsoft/raven/-/blob/8451723565744f145d5c0048d3774f9751e59792/ligo/raven/search.py#L244 to include this.
