A large-scale Internet outage in Israel is a possible cause.

Cybersecurity specialists are engaged in identifying vulnerabilities in the system, which could lead to the absence of Israeli Internet providers.
Today's failure of Internet networks in Israel turned out to be large-scale and affected the country's key communication systems, rather than being a local malfunction.

This is reported by the Israel Hayom newspaper.

First, Partner's cellular network and Internet stopped working, then Cellcom, HotMobile and other services that depend on different providers joined the failure.

According to preliminary data, the problem occurred at the DNS system level, which maps host names to IP addresses and routes traffic, presumably due to a failure of the Cisco router used for data routing.

Data center engineers reported that switching routers restored access to some services, including cloud platforms, while some websites and systems continued to work without interruption. Experts continue to analyze the impact of content delivery networks and Partner's internal server farms on the outage.

Currently, there is no official confirmation that a large-scale failure of communication networks was caused by a cyberattack. However, the probability of such a scenario is increased by the fact that the failure affected both fiber-optic Internet networks and cellular communications.

The incident is currently being reviewed at the technological, regulatory and security levels.

The failure once again highlighted the vulnerability of Israel's strategic communications systems to large—scale attacks that could cause serious damage to the economy, security, and critical infrastructure from hospitals and banks to transportation and water supplies.

Earlier, Cursor wrote that in recent hours, an unusual incident was recorded in the Israeli telecom sector, which seriously affected the operation of the infrastructure of several operators.
