Upgrading spike doubled some ISP traffic; 12 percent worldwide Internet
usage jump


Analytics company Mixpanel estimates that more than 130 million users
had updated their devices within the first 10 hours of availability, out
of a potential iOS 7-eligible base of 415 million.


The spikes, reported by The Guardian in the UK, focus on British ISP
reports and show that demand hit its peak about 3.5 hours after the
official release. This would have been around the time Apple servers
began to recover from the initial wave of downloaders as users struggled
in the first few hours to download the free iOS upgrade, which ranged in
size from 750MB to 1.4GB depending on what device was being updated.


At one point in the initial surge, a British Telecom (BT) spokesperson
reported that the provider was seeing traffic of over 200 Gigabits per
second, the highest the company has ever recorded. Lonap said that
overall high-use traffic, which averages up to 30 Gigabits per second,
spiked to just under 60Gb per second late Wednesday evening as the
upgrade became available, and raised the daily peak time traffic to
nearly 40Gb per second on Thursday.

The paper also reported that Germany's Berlin Internet Exchange saw
traffic rise precipitously -- more than 10Gb per second over normal
traffic levels -- as iOS 7 came online. Data from Akamai, a company that
distributes and manages Internet backbone traffic, suggested that
overall worldwide usage jumped 12 percent above normal levels as the
download became available.
