This is really annoying... Down 2 times in 3 days!

Have they broken your SLA?

Linode has a 99.99% uptime guarantee, which amounts to 43 minutes and 12 seconds offline in a 30 day month. While I don't have a Linode in Freemont, their status page appears to indicate, at minimum, 1 hour of downtime. As repayment for the inconvenience, users get the lost time added to their balance.

A 99.99% uptime guarantee would be 4.32 minutes per month. You calculated for a 99.9% uptime guarantee.

I'm going to take a long break from ever doing math again on HN.

With 99.99% uptime:

.0001 * 30 * 24 * 60 = 4.32 minutes

With 99.9% uptime:

.001 * 30 * 24 * 60 = 43.2 minutes

I think he just typo'd the %. From the terms[1]:

    Linode.com provides a 99.9% uptime guarantee on all Linode hardware,
    and on network connectivity. In any given month, if your Linode is
    down for more than 0.1%, you may request a pro-rated credit for the
    down-time.

Wait so the only backlash they get should they break their guarantee is that they credit me for the down time? This doesn't seem like a motivating factor to keep uptime. Is this standard practice in the industry? I know prgmr has refunded me the entire month when they broke their SLA.

All that said, I won't be getting rid of my Linode box in Fremont simply because it's one of the best vps's I've had performance wise. It just seems like an odd SLA.

It's a term of service (TOS) agrrement, not a professional SLA.

Most of us don't pay Linode anything important enough to warrant an SLA.

You don't get very strict 99.9% SLAs for $20 and $80 a month anyways...

Actually their SLA is only 99.9% uptime. Thats 525 minutes.

They were down for us nearly 6 hours Saturday night, 1 hour this morning. They broke their SLA by a mile. Moving to EC2 asap.

What is EC2's SLA, and what cases of downtime have they experienced over the past couple of years? I'm assuming you wouldn't change providers without first finding this out?
