A bit of a tpyo

Published on: 11 Mar 2017


We’ve all done it. Pressed the wrong key on the keyboard and before you know it you’ve sent an email or report with a typo in it.

Most of the time these are fairly harmless. This, together with spellcheck facilities means that normally it’s not a major problem if there’s the odd typo.

Unfortunately though, if you’re a software coder then a typo can have a major impact.

Cloud services are where companies store their data on remote servers held by companies such as Amazon, Google and Microsoft.

Last week, numerous websites which use Amazon’s cloud servers went down. These were major websites such as quora.com and soundcloud.com. Amazon subsequently revealed the problems were down to an employee who was trying to fix a software bug in a billing system but typed in the wrong string of characters.

Amazon said that “the command was intended to remove a small number of servers. Unfortunately, one of the inputs was entered incorrectly and a larger set of servers was removed than intended.”

Amazon quickly resolved the issue though and stated that they had “added safeguards to prevent capacity from being removed when it will take any subsystem below its minimum required capacity level. This will prevent an incorrect input from triggering a similar event in the future.”

There are lots of advantages of using cloud servers but as this illustration highlights there are also disadvantages.
