doesn't "see" new commits

Yesterday everything was fine, but today I noticed that all my pushed commits don’t appear on
Is there any technical work in process?
Last visible commit on GitLab is 18 hours ago, but I pushed 4 commits during last 4 hours and they don’t appear on although running git status locally gives me Your branch is up-to-date with 'origin/master'.

After pushing once again everything works as expected. It was strange.
