S3 outage

Sunday, July 20th, 2008

Amazon S3, which is where we host most of our images, is having some problems at the moment. We’ve switched over to our backup systems, so things should be working fine. However, panoramas embedded in external sites may have some problems while the DNS updates. We should get everything back once Amazon has fixed the problem.
Update 0839 BST: S3 has been restored. We’re currently syncing our servers with them, so everything should be running smoothly soon. Thanks for your patience.

Amazon S3 outage

Friday, February 15th, 2008

All of the panoramas on CleVR, as well as swfs and thumbnails are hosted on Amazon’s Simple Storage Service (S3). This has always been very reliable for us, but today they’ve been having a major outage. Currently it has been down for around 90 minutes, and they’re not giving an estimate of when it will be fixed. We have moved everything to our other servers, so things should be working fine. However, some people may experience issues where the old DNS information has been cached by their servers. Please bear with us, and it should update within an hour or so. Of course, if Amazon fix it then it will start working before that.

For those who are interested, the status information from Amazon can be found here.

If this image works, then Amazon s3 is working again:

Update 1510 UTC: Seems it’s all up again now. We’ll switch back to S3 in a bit when we can be confident it’s staying up.

Amazon S3 pricing changes

Tuesday, May 1st, 2007

Here at CleVR, we use Amazon’s Simple Storage Service (S3) to host all of the panorama image files. This is a truly excellent service that helps us scale really easily without needing to buy loads more servers and RAID arrays and so forth. It’s great for small companies like ours, as well as not so small ones. The pricing is really simple: $0.20 per GB uploaded or downloaded, plus $0.15 per GB per month for storage. The guys at SmugMug reckon that they’ve saved $1 million in a year using S3. Anyway, one of their complaints was that there’s no volume discounts.

This morning I got an email saying that they’re changing the pricing model, and it looks like it should save most people money. They’ve introduced volume discounts, cut the headline transfer costs, but added a per request fee. It breaks down like this:

New bandwidth price (effective June 1, 2007)
$0.10 per GB – all data uploaded

$0.18 per GB – first 10 TB / month data downloaded
$0.16 per GB – next 40 TB / month data downloaded
$0.13 per GB – data downloaded / month over 50 TB
Data transferred between Amazon S3 and Amazon EC2 will remain free of

New request-based price (effective June 1, 2007)
$0.01 per 1,000 PUT or LIST requests
$0.01 per 10,000 GET and all other requests*
* No charge for delete requests

Storage will continue to be charged at $0.15 / GB-month used.

Now, we’re not big enough yet for the volume discounts to kick in (but here’s hoping), but this seems like a very sensible change. Costs for a request are generally broken into bandwidth and per request (CPU, memory etc), so it makes sense to unpack them like this. I haven’t done the maths yet, but it should save us money right now, and it could save a lot once we get really big (come on, tell your friends!). Another reason to love AWS!
