Issue 710577 may be a contributing factor. Please note the issue was present in some way for about a week already. An outage in last day or two wouldn't fully explain it then.

https://chromium.googlesource.com/chromium/src/+/refs/tags/58.0.3029.51/DEPS is there..

I used a sequence of:
git checkout -b auto_release_branch aba3eb683b30adce02c5be41e84c431dac599c59(commit that updated chrome/VERSION to 58.0.3029.51 on branch 3029)
git commit -a -m Publish DEPS for Chromium 58.0.3029.51
git tag 58.0.3029.51 HEAD -f
git push origin refs/tags/58.0.3029.51

Should I push tags in some other ways?

Logs:
for 'git push origin refs/tags/58.0.3029.51'

from Step 10 on https://uberchromegw.corp.google.com/i/official.infra.cron/builders/chrome-release/builds/136

All those tags exist on the master. Note that --with_branch_heads and --with_tags are different things. You might need to add the latter.
