A Paltel employee, speaking anonymously as the person was not authorized to talk to the media, told POLITICO on Friday that repairs were unlikely due to ongoing bombardment and a lack of equipment and supplies. Moreover, he said the company’s workers in Gaza were sheltering and struggling to stay in contact.

The shutdown could be a precursor to the widely-anticipated ground invasion of Gaza, where residents have already suffered large losses from air strikes and targeted raids. Israeli military spokesman Rear Adm. Daniel Hagari told reporters Friday that ground troops were “expanding their activity” in Gaza and that it “is acting with great force … to achieve the objectives of the war.”

NetBlocks and internet traffic group Cloudflare were among the organizations to track a sharp decline in connectivity in Gaza on Friday. David Belson, Cloudflare’s head of data insight, said in an email that the company had seen “traffic declines across several of the Gaza Strip governorates,” and had tracked the complete drop-off in traffic of almost a dozen major internet service providers in Gaza since the Oct. 7 attacks.

Alp Toker, founder and director of NetBlocks, said Friday that his company had tracked “the single largest disruption to internet connectivity in Gaza today,” warning that the “situation for many will be a total or near-total internet blackout at this point.”

“Today’s outages are due to the bombardment, direct damage,” Toker said. “We have confirmation from the operator now that this was kinetic impact, and the terms are consistent with a sudden outage.”

The IDF did not respond to a question from POLITICO as to whether its airstrikes or raids had targeted internet providers. However, it did provide a statement saying that it had expanded strikes in Gaza “in the last few hours” and that the Israeli Air Force had struck “terrorist infrastructure in a significant way.”

A spokesperson for the Israeli Embassy in Washington, D.C., did not immediately respond to a request for comment on the lack of internet connectivity, and the State Department did not respond to a request for comment.

Critical infrastructure has been a major target of attacks during the Israel-Hamas conflict. An Israeli airstrike destroyed Gaza’s only power plant in 2014, and Israeli airstrikes in recent weeks have targeted at least 7,000 structures in Gaza. Paltel has struggled to provide service in recent years, shutting down phone and internet service to Gaza in 2017 in the middle of an electric power crisis. Hamas reportedly took down at least four Israeli communications towers on the border of Gaza as part of the Oct. 7 attack.

News service Al Jazeera told POLITICO they are still able to broadcast and communicate from Gaza using satellite connections.
