back to article Unexpected MySQL database meltdown fingered in GitHub's 24-hour website wobble

Programmers, your snow day is well and truly over: GitHub's website has finally cleared its 24-hour outage, and reckons everything is operating normally again. Last year, CEO Chris Wanstrath said the company was shooting for zero downtime, or at least five-nines of uptime. Well, that comes out at about five minutes of non- …

    "only impacted website metadata stored in our MySQL databases"

    ... which of course is the only valuable part of Github.

    The actual repository data is completely mirrored in every single git checkout that you have.

      Will be an interesting migration project, until then MS will be running using Oracle software.

      Hint: if you think you need MySQL consider Maria first, avoid getting larried.

        Avoid problems altogether and switch to Firebird ...

          Firebird looks great and something I need to get under my hat.

          Thanks for the heads up.

    MySQL on a production system?

    Insert sneering remarks here…

    Elsewhere it looks like Atlassian had a couple of hiccups yesterday as well. At least the post-commit hooks didn't seem to kick off Pipelines.

    THEY SAID FINGERED! The politically correct crowd will be along shortly to wring their hands & whine at ElReg ... What ever shall we do!?‽‽

    No MySQL replication slaves for failover?

    Any competent DBA will tell you that you should be running multiple replication slaves of any mission-critical MySQL database server, and they should be using different back-end storage systems than the master. These replication slaves can provide read-only copies for load-balancing, and can also be promoted to become a read/write master in the event that the master suffers a hardware failure.

    Someone at GitHub/Microsoft evidently didn't get beyond chapter 1 of the "How to be a production MySQL DBA" notes.

      GitHub is a typical Silicon Valley "success". Written quickly using Ruby on Rails, became popular and attracted VC funding and subsequently sold to Microsoft. Do you think there was ever a DBA involved?

      Must be fun to be Microsoft, to get the blame at a company they only bought a couple of months ago, for a problem that was probably set up to fail by decisions made years ago...

    To be fair they have a very talented and well-respected MySQL team at Github.

    I would reckon the issue possibly with their Orchestrator open source tool https://githubengineering.com/mysql-high-availability-at-github/ https://github.com/github/orchestrator

    Time for NewSQL?

    How about using a truly distributed, always available, active-active SQL DB like CockroachDB (if one want to stay with open source)? Come on guys, let's keep the innovation spirit alive.

    Five Nines

    OT, but that reminded me of the "pep talk" we recently acqui-hired remnants of a once-promising startup were given on arrival at the (larger head-count than the town I grew up in) megacorp. The speaker was the (insert plausible title translating to "high muckety-muck") of global marketing, and he reassured us that the emphasis will still be on commitment to quality and reliability, promising we would deliver "nine fives". A fellow newly-borged coworker and I looked at each other, agreeing that this lot could probably achieve it.

    Coincidence? I. Think. NOT!
