I can't help to think that Gitlab is more and more eating Github's lunch. I wonder why we see so little from Github to get out of that situation.
While I'm glad to see competition gearing up, I don't think GitHub and GitLab are in the same ballpark yet. While I'm a big fan of their team and culture approach, we yet to see better/respected GitLab.com SLA guarantees — it still feels like they're doing too much "testing on production".
Agreed. However, if you need more reliability than gitlab.com it's not difficult to host GitLab yourself in a VM or on bare metal.
Many companies already have their own physical servers in a DC (either colocated or leasing). Hopefully the people managing these servers know what they're doing and can give the developers a good SLA. Although some additional work on file/DB syncing would be necessary to have a hot spare.
