From the imported projects graph, looks like there was a spike, then it settled back to normal.
Normal only because the scale of the graph is totally skewed right now. Looking at actual values, it looks like they're currently at ~2400 projects imported per measuring increment, up from <100 per increment before the Microsoft rumours first popped up, and down from 24k in the big spike.
Genuinely curious what features of a GitLab or GitHub equivalent you would require in a self-hosted scenario that 'git' doesn't provide?
I would expect other cloud providers to offer the same or more but include ads or I would have expected 10 subpar offerings but with a free price tag.
