Now that sysadmin guy who told me: "what happens when bitbucket goes down?" when I asked him to move our repos to the cloud, he is smiling. Sometimes it's best to keep stuff in your own servers, if you have any...
We have Bitbucket on our own servers, and we're moving it back to either Atlassian's hosting or to Github. The reason being that we spend far too much time per month hand holding the server when it goes mental and takes all of the RAM and then decides not to server any pages. And it's not for a lack of resources on the server either, 16Gb RAM and 4 core virtual machine, running Linux.
So we have more downtime than either Github and Bitbucket combined.
Any guesses why that happens? It's weird that a git server goes mental just to serve a repo. We had gitlab on my previous job and git server on my preprevious job and never ever had server down problems. This period is like 5 years total.
What about when your server and stuff goes down? Or has a bug or issue that causes downtime or similar issues? Your servers could have better uptime than Bitbucket, but maybe not.
not that your own servers are up 100% all the time. But the reserve in that case you could be smiling at the sysadmin guy while he scrambles for a fix, he is just happy not being at fault and having to fix it ;-)
