We do slow rolling updates for all the servers in operation. In most simplest terms this means only some of the servers are updated at a single time.<\/p>\n
Updating process depends on how major an update is and how critical it is. If it’s just a tiny update and most servers are already on the latest major revision we might do a big bulk update of most of the servers. On the other hand, if it’s a major update then we do only a small number first.<\/p>\n
Small updates have no, or very small chance of\u00a0regressions<\/em>, ie. new bugs introduced to the system, while major updates have a\u00a0big chance.\u00a0<\/em>This means on big updates we need to be careful and slow on the rollout.<\/p>\n Same reason is why we try to avoid doing major updates too frequently. There is\u00a0always<\/em> something that breaks when you do an major update.\u00a0For example,<\/em> we lately updated ruTorrent and this has resulted in hundreds upon hundreds of tickets, and even some service cancellations.<\/em> Reason? Despite our best efforts to force browsers to revise their cache, most stick to the cached versions resulting in ruTorrent javascript failing. Despite using\u00a0every method<\/em>\u00a0to tell the browser update the jquery javascript library.<\/p>\n No developer can achieve full QA themselves, there is simply too varied use of any system. With slow rollout we gain\u00a0invaluable<\/em> feedback and catch potential usability issues before it is affected by the vast majority.<\/p>\n Every user is different, that’s why the same person developing the software may not notice even the\u00a0most obvious<\/em> issues. What works on Windows\/Chrome combination may not work on Ubuntu\/Firefox.<\/p>\n Our software backdates to when Debian 5 was new and fancy. There are still servers out there running Debian 5,\u00a0despite,<\/em> support for Deb 5 was dropped a long time ago. Same goes for Debian 6, and soon Debian 7 will move to the history as well.\u00a0So far,<\/em> there’s a lot of things which needs to be tweaked for Debian 8 before it becomes supported, and at the same time we need to also support Debian 6 and 7.<\/p>\n This means we need to support a variety of versions, configurations etc. out of the box.\u00a0Quite simply,<\/em> it is impossible to update every and single server at the same time for Debian 8 – Especially those out of our control but using our software package.<\/p>\n","protected":false},"excerpt":{"rendered":" Rolling Updates: The What & Why We do slow rolling updates for all the servers in operation.
