The Cloud is falling, the Cloud is falling! Amazon, Walmart, Salesforce and others down on December 23rd

A Major pre-christmas internet outage seems to be hitting the heavy hitters on the web right now. Amazon.com, Salesforce.com, and Walmart.com are all offline right now, perhaps even more. Interestingly enough sites running on amazon web services (AWS EC2) seem to be running just fine. An outage of these large sites at the same time is likely a result of an attack of massive proportions.

UPDATE: It appears the outage was actually isolated primarily to the west coast of the US, and was actually an outage of ultradns.com which provided dns for all of the above sites and many others, including netflix and newegg.

EC2 and S3 never actually went down, but S3 urls that actually used s3.amazonaws.com were not functioning, so while many sites with S3 images stopped loading, twitter, which also uses S3 for image hosting did not have a broken image because they had their own dns pointing to S3’s ips. I also didn’t notice the EC2 servers being down, but that was because I access EC2 servers with other dns names, not amazonaws.com, had I tried to access them using amazonaws.com urls, I surely would have had difficulty.

GMail Down

GMail Down
In the latest in my ongoing series of Major websites experiencing outages, GMail has been down for at least the last hour. Google’s Mail service is excellent and over all I’ve always been pleased with it. Their servers are redundant, I don’t have problems with lost email messages, and the spam filtering is second to none. I also am a big fan of the search, filtering, and conversation features that make it the best email experience I’ve ever had, but today, it’s down, and I can’t access my email, which again slows down my productivity. But I take it as a bit of comfort, because the next time one of my sites goes down I’ll remember, even Google has server outages sometimes.

It’s important to note that while the web interface (which I primarily use) is down, the IMAP appears to be fully operational, so I’m still getting new emails buzzing on my iPhone constantly, I just much prefer to work on the web based interface with all of the search functionality that makes it easy to find just the right message when I need it. I hope the server comes back up again soon.

Also before some jerk calls me a fool and tells me that I’m screwing up with my urls, it’s not just me, None of my coworkers are able to get on GMail, neither can my wife (who is not here), nor several friends online. A Simple Date Based Google Blog Search shows that many other people are experiencing problems with 502 errors on the GMail interface today

Update: After getting everything operational again, Google Blogged about the outage, apologizing for the inconvenience.
