Apple released iOS 10 this evening, and looking at our traffic stats customers started downloading it at 6pm on the dot! Our network is coping with this increased load but it does look like it'll be the busiest evening we've ever had.
Looking back over the course of the evening BT connected lines look mostly unaffected, however some TalkTalk connected lines suffered with about an extra 30ms of latency and a decrease in download speeds. This was caused by one of our links to TalkTalk running at full capacity.
