    Has anyone done any sort of bandwidth study looking at sites like etrade and yahoo, for purposes of determining any correlation between bandwidth consumption and movement on the stock markets? Intuition says that Monday mornings ought to see some sort of correlated spike.

    Sounds alot more like lack of a proper devlopment environment to me.

    I mean its easy for it to happen. We had problems like this with our monitoring system (tho it was manic friday where someone would attemtp to impliment something before the weekend because of course, the weekend is when you want pages the least so you want to get anything that causes false pages fixed on friday to maximize enjoyment of the weekend)

    Now we have development and test servers where things live BEFORE they go production. I never had any idea that it would help so much until we finnaly implimented it.

    Just a thought: The rest of the world lumps all of us IT people together; the distinction between, say, a "developer" and "sysadmin" means nothing to my non-geek friends.

    I don't think stuff like this happens often to sysadmins or DBAs. How often do you come into work on a monday and decide to migrate to xfs because you read on slashdot over the weekend that SGI ported it to linux, and SGI is cool? Likewise, how often does an Oracle DBA decide on Monday to move some production tablespaces over to rawfs from cooked, because she read a whitepaper from Oracle on Saturday that talked about performance increases from raw filesystems?

    I've written a lot of code, and also sysadmin'd an awful lot of servers, and in my experience probably 90% of "production outages" are software changes--exactly like the article said--poor change control, etc etc. So, what's the point of dynamic multipathing, patching, dual power supplies, etc etc, when most problems occur because someone got excited and forgot a semicolon somewhere?

    Is it fair to say that sysadmins fix things and developers break them? What is different about a software engineer's brain than a systems engineers? Talk amongst yourselves :)

    On retail and B2B sites, Monday is usually a busy day. Customers are rolling into their offices with articles to read, facts to research and stuff to buy. Out of the seven days of the week, it'd be the worst for making a change.

    On the other hand, I'm not sure incremental development is that much worse than large releases. You're either releasing a bug or two a week or waiting eight weeks to release all your bugs at one time.

    While working for a large nameless Telecoms Company,
    I and my fellow Contractors had an unwritten rule to "hold off" on all "good" ideas generated in meetings etc on Monday & Friday. Almost inevitably they would
    all be canceled within a couple of days. Not subjecting ourselves to post/pre weekend madness saved ourselves a ton of work and helped us bring the project in on time!!

    Indeed.

    A Google search for even the word "website" came back with: Results 1 - 10 of about 68,800,000.

    Even with that number, which I would estimate to be low of the total number of websites in existance, that puts the 70 site survay at .0000102% of all the websites (Granted those are pages but you get the idea.) in the world.

    Mr. Gandhi has his cause and effect a little mixed up, and I think he's implying that new development shouldn't ever introduce new bugs, which is a little silly.

    For the concrete "holiday lockdown" example, I think he's only partially right. In my development group, we explicitly lock down ALL changes to our production web apps well before, and all through, the Christmas shopping season, to prevent the inadvertent introduction of any (new) bugs. It's not a side effect of vacation time -- it's an explicit operations decision to reduce the risk of breakage.

    So, yeah, while we're not touching it the stability seems to increase, but no existing (but less critical) bugs get fixed either. No large-scale app is bug-free -- the lockdown period just seems to stabilize things but it's an illusion caused by the lack of new species of bugs popping up.

    In the more abstract "development introduces bugs" sense, it's a fact of life in complex systems that new code means new bugs -- and if we never introduced new code (->features) then we'd lose customers. So I take his statement to imply that we should only be introducing 100% bug-free code -- which is a PHB pipe dream.

    I, as IT director, would fire my IT staff if they pulled this. Considering that I have some systems with uptimes in YEARS, a few going on a DECADE, and over-all the _entire_ network has worked 24x7 for the last 10 years. Our business operations isn't even Internet based (we just happen to use it -- primarily for email) and the operations of the systems isn't life-critical. We just like our computers/networks to work.

    Of course I'm the one that implemented a testing domain (live on the Net) for just such purposes. NEVER, NEVER, NEVER "test" anything on a production system. I can't even think of any installations that were not tested for MONTHS "offline" before being implemented. When the day comes to install there usually aren't any shockers either. It just works.

    Of course I'm the one that's NEVER allowed a Windows server to even be a consideration. "Are you NUTS?"

    I'm going to start with pointing out that the first sentence of the article said "UK websites", not "US". Obviously that means the people across the Pond need to work on this.

    And what a surprise that when people roll out changes sometimes things break. Oh My God. Have you cured cancer yet?

    And I'd say more often than not the "problems" on Monday are caused by bug fixes that developers are rushing on to production to fix bugs that were found over the weekend. And, as we all know, sometimes bug fixes skip QA...

    Seriously, most places I work have Go Live set to be Monday, or, more often, Tuesday. You go live when you have already tested it; its gone through QA; and you're sure the staff is there. Tuesday is the better date in order to deal with key people taking long weekends, and it gives you two or three days to fix issues before the next weekend. Besides, Mondays are already hellish without adding "release new version" to the list of torments.

    When I was responsible for the Internet site of a rather large national bank, we only accepted change requests for Tuesday and Thursday mornings. It was just easier for the operators to get hold of a sober developer/administrator at 02:00 on a Tuesday or a Thursday than any other time. And getting a contact on the business side to ok a rollback that caused contract issues on the weekend was near impossible.

    That's fine and dandy if you have an large IT staff to do all that, but most of my friends have jobs where there are less than 3 people doing all the development, myself included.

    I enforce upon myself the requirement to run new code on a test server first, but a formal and managed development environment just isn't going to happen at small companies, or larger companies with small dev staffs.

    Then there is also the issue of things that are extremely difficult to model in a test environment. Complex failures. Failures that may not show up in a unit type test, but only show up when components interact. It is possible to model some of these things, but sometimes the unit testing code would be larger than the code under test. This is also not practical for a smaller development group.

    The correct precedure for an update should be at minimum:

    • Lightbulb above head in the weekend (ding!)
    • Over the following week, research the change, check impact on existing systems, come up with a maintanance strategy, document it, inform people, test it in a lab, plan the implementation, develop a rollback procedure.
    • Implement change early the following week - never on a Friday, preferably not on Thursday.
    • Watch throughout the week for problems.
    Anything less and you dont deserve to be in that position.

    First, day traders or the public in general is such a small part of the capital markets that they don't even register a blip on the radar. Even if someone had a million dollar portfolio they still are up against institutions with billions of dollars. So in effect, the mass public is irrelevent.
    Second, I don't know about bandwidth studies but you will find that most of the activity in the markets takes place on the open or on the close. Mid morning and mid afternoon markets are generally dead.

    Also, to do a bandwidth study just take the intraday volume of a stock and correlate it to that of etrade or yahoo.

    Not only does my company have an extensive change control system in place, but until very recently, we had a "no changes on Monday" policy. Since Monday is our busiest day, it made good sense. In fact, we couldn't even run network cabling for new servers on Mondays. There were little signs all over the building that said, "A Monday without change is like money in the bank!" Kinda cheesy, but it seemed to work.

    We recently dropped the policy, but I'm not sure if there has been any fallout from doing so.
