While not nearly as badly off as most of North America, we're set to experience a record-setting heat wave here around the Nightmare Factory. While we're pretty good at heat management, we do not have full A/C, and the Murkworks may have to shut down some servers during peak heat times of the day. This will happen with relatively little notice. The order of shutdown will be, as necessary: backup services, web services, mail services, then DNS and complete network, in that order. Temperatures are expected to return to ranges more approximating normal this weekend.
Last year when we went through this we stayed up, except for backup services, throughout the entire heat wave, then had a power outage just as things cooled down. It was sad.
