Real impact

Sometimes the impacts of a bug are really interesting and easily measurable: On Tuesday i got a mail from the company that hosts that the electrical power consumption of their total operations increased by one megawatt in the night from 30.06 to the 01.07 and that they are asking for a reboot of the systems (however: just setting the time suffices). Ouch. The reason: The issues of numerous Linux Distribtions in regard of handling the leap second. Hetzner as a hosting provider operates large masses of such servers (partly as customer-administrated dedicated servers) and so it adds up. Kristan Koehntop pointed to an interesting chart in his google+ feed, that nicely shows this hike in power consumption
