In late January, as China locked down some provinces to contain the spread of the coronavirus, average internet speeds in the country slowed as people who were stuck inside went online more and clogged the networks. In Hubei Province, the epicenter of infections, mobile broadband speeds fell by more than half.
In mid-February, when the virus hit Italy, Germany and Spain, internet speeds in those countries also began to deteriorate.
And last week, as a wave of stay-at-home orders rolled out across the United States, the average time it took to download videos, emails and documents increased as broadband speeds declined 4.9 percent from the previous week, according to Ookla, a broadband speed testing service. Median download speeds dropped 38 percent in San Jose, Calif., and 24 percent in New York, according to Broadband Now, a consumer broadband research site.
Quarantines around the world have made people more reliant on the internet to communicate, work, learn and stay entertained. But as the use of YouTube, Netflix, Zoom videoconferencing, Facebook calls and videogaming has surged to new highs, the stress on internet infrastructure is starting to show in Europe and the United States — and the traffic is probably far from its peak.
“This is totally unprecedented,” said Thierry Breton, a European Union commissioner who oversees digital policy and was a chief executive of France Télécom. “We have to be proactive.”
To head off problems, European regulators like Mr. Breton have pushed streaming companies such as Netflix and YouTube to reduce the size of their video files so they don’t take up as much bandwidth. In the United States, regulators have given wireless carriers access to more spectrum to bolster the capacity of their networks.
Some tech companies have responded to the call to ease internet traffic. YouTube, which is owned by Google, said this week that it would reduce the quality of its videos from high to standard definition across the globe. Disney delayed the start of its Disney Plus streaming service in France by two weeks, and Microsoft’s Xbox asked gaming companies to introduce online updates and new releases only at certain times to prevent network congestion.
“We really don’t know how long we’re going to be in this mode for,” Dave Temkin, Netflix’s vice president of network and systems infrastructure, said in a webinar on Wednesday on how the coronavirus could affect internet infrastructure.
Internet service providers like Comcast, Vodafone, Verizon and Telefónica have been building out their networks for years to account for increasing demand. But company officials said they had never seen such a steep, sudden surge. Growth that the industry had expected to take a year is happening over days, said Enrique Blanco, the chief technology officer at Telefónica, a Spanish telecommunications company.
“In just two days we grew all the traffic we had planned for 2020,” Mr. Blanco said.
