Hello @atalhinho
If you are working at Galaxy Main https://usegalaxy.org, yes, there were server issues earlier that are now resolved: https://usegalaxy.org/ -- Server issues Feb 25, 2020 Resolved
Jobs that are queued should start up again on their own. Any jobs that fail (for any reason during this time frame) should be rerun. See the post above for more details.
Thanks!
