We regularly experience “503: Service Unavailable” on git.kolab.org as of late, even though the system is more up to date, and both fatter and leaner. Fatter, because more resources are allocated to it. More CPU, more memory, larger APC, opcache, and database services got separated out from the system, and put on to a MariaDB… Continue reading 503s on git.kolab.org
It’s been a while since we last updated Phabricator, and it’s been a while since the overall system that runs git.kolab.org was paid attention to.

You’re welcome to provide us with feedback on the Kolab Hub Beta Program forum, but feedback does… Continue reading Kolab Now Beta Program: An Update
I’m pleased to be able and allowed to introduce you to the Kolab Now Beta Program, which my colleagues and myself can use to deploy newer versions of software sooner, faster and with less strict guarantees of availability and stability (i.e. the concept of a “service window” does not apply). The first feature to be… Continue reading Introducing the Kolab Now Beta Program
