Reddit's been down for several hours today, I'm sure they are already way lower 99.95%.

0.05% of one year is 4 hours, 22 minutes and 48 seconds.

  Which means their entire quota for this year is all gone.

  Don't forget to take in to account ALL of Reddit's downtime; there is quite a bit of it.
- cmurdock 16y ago
  Reddit experienced some issues with Amazon a month ago that resulted in the site being down for almost a day. I'm pretty sure they're way below that percentage.

    That's conflating SLAs again, Reddit's long-running problems have been with EBS reliability.
    - cube13 16y ago
      Even so, .5% downtime per year is about 44 hours, and Reddit's definitely had more downtime in the last few months than that. Of course, that's assuming that 100% of Reddit's problems were due to EBS only and not a combination of EBS, EC2 and their own code.

  Is this really standard practice for measuring the SLA? The contracts I've seen for a couple small businesses are generally per billable period. Which always made sense to me. I pay you for 99.5% uptime this month. If you don't achieve it, then I get a discount, as simple as that. If your availability is below that, I don't pay full price for the billable period and then reconcile at the end of the year. Any links or general advice on this topic anyone has I'd be pretty interested on finding out if there's a general consensus of it being done differently?

If the Reddit web server admins took availability seriously they would have chosen to deploy across more than one region. Do you disagree? Why do you disagree? I'm being honest, no snark involved in my questions.

  The whole point of AWS is to forget about maintaining hardware infrastructure. Amazon are the ones who should have made backups in multiple regions, and transfer the load on failure.
  - edanm 16y ago
    "[S]hould" is the wrong word here. Clearly, they don't maintain such backups. This is clear to anyone using their service. They pay for the service anyway, so apparently it's still worth it to them, even without auto-backups. Would it make sense for Amazon to maintain automatic backups (and potentially charge more for them)? I don't know. It might make business sense, it might not. But their service is apparently popular enough even without it.

    Actually, the whole point of AWS is to have options for using hardware that you don't own. They don't offer any magic "all your stuff in one package, guaranteed to work all the time" service. So yes, you do still need to think about your hardware infrastructure. You just don't have to own it. And Amazon does have all their stuff available in multiple regions. It's up to you to use it though.

    Not sure if I could say Amazon should be doing that - but I'd love it if other value added providers (such as Heroku) could implement this.

Reddit being down is not news.
- davidreiss666 16y ago
  No. Not really. But we kind of miss it anyway.
- jedberg 16y ago
  That hurts. But you're right, we've had a lot of issues. I think the reason this is news is because it is a massive Amazon failure.
  - Peroni 16y ago
    Reddit gets a lot of grief for stability issues but the fact is it is an immensely popular site that a huge number of people have a close affiliation to. A massive percentage of these people spend a significant portion of their day browsing Reddit, interacting with other redditors, etc. and for the site to be down for as long as it has is news, regardless of similar issues occuring in the past. The main reason this is news is because this is an Amazon issue but also because tens of thousands of people who frequent the site regularly are now aimlessly browsing the internet in the hopes of finding alternative lulz and in my case some of us are even getting work done. shudder

    I can't imagine how frustrating the jobs of the Reddit admins must be.
    - jedberg 16y ago
      It's usually very rewarding. The awesome community is what keeps me doing it.
      - freakball 16y ago
        Awesome, I just figured out that you kept the votes tallied during the 'downtime'. What's interesting is how clearly good and bad submissions were dichotomized when nobody had anything else to vote on.

http://cache-scale.appspot.com/c/www.reddit.com/ http://cache-scale.appspot.com/c/www.reddit.com/ That's a cache of it. I really wish that the admins at reddit would implement something like this themselves, then link to it when downtime like this happens.
- wallnutboy 16y ago
  They do have a read-only mode, don't they? I'm not sure why they don't enable read-only mode when things like this happen. It may be that Amazon's service being down forbids this. I dunno.
  - groovylick 16y ago
    They have a read-only mode for "free" which is their akamai cache that the unlogged in users see.

  do you have any stats of this app in terms of total data stored, bandwidth required per day, requests per second?
  - blhack 16y ago
    I don't, unfortunately, because I didn't write it :(
