Telecom Spectrum and Security

Within the Topic facet, Telecom Spectrum and Security topic intelligence connects articles that share a specific subject, signal focus, or monitoring theme. The page gives readers a richer path through related reporting, source evidence, market actors, and infrastructure implications, with enough context to understand why the topic matters across company movements, governance decisions, regional exposure, and operational risk. Readers can compare recurring signals, affected organisations, public evidence, market context, service continuity, procurement, competition, compliance, and strategic planning questions behind the subject instead of stopping at a thin list of matching articles. It explains what the topic covers, which infrastructure actors or policies are involved, what evidence supports the coverage, and why the subject may matter for operators, customers, investors, and policy readers.

OVHcloud made anti-DDoS maintenance a BGP-to-OSPF change-control failure

OVHcloud's October 2021 outage began with planned work intended to strengthen anti-DDoS protection, but the public record describes a routing-control failure rather than a successful attack. A command affecting redistribution from BGP into OSPF caused the full Internet routing…

KDDI's 2022 VoLTE outage: when recovery control became the accountability test

A routing error during overnight maintenance lasted only long enough to start the incident. The nationwide service crisis that followed was sustained by something harder to unwind: repeated location-registration requests, congested VoLTE call-control nodes, overloaded subscriber…

CenturyLink's 2018 outage showed how an unused management channel became a national failure path

Four malformed packets should not be able to disable a national communications network. Yet in December 2018, four packets generated at one CenturyLink node entered a management channel that the operator knew about but did not use, spread through connected equipment, and helped…

T-Mobile's 2020 outage showed how one fiber failure became a national routing cascade

For more than twelve hours on 15 June 2020, a communications failure that began with one leased fiber link spread far beyond the place where the cable problem occurred. Calls failed, text messaging was disrupted, and thousands of attempts to reach 911 did not arrive at public…

4,407 exposed Rockwell controllers reveal a routing problem, not 4,407 victims

Forescout found 4,407 internet-facing industrial controllers exposing EtherNet/IP in an August 3 query, with a striking concentration on US mobile-carrier networks. The count measures reachability, not compromise. Its value is to show where asset owners, carriers and public…

BT's 2023 999 outage showed why an unexercised failover is not emergency continuity

For people trying to reach the UK's emergency services on 25 June 2023, the distinction between a primary platform and its backup was meaningless. What mattered was whether a call connected. BT's emergency-call service was disrupted for approximately 10.5 hours, including a total…

Lumen's 2022 Dakota 911 outages showed why backup paths need a real dependency map

Emergency calls failed to reach 11 local 911 centres in western North Dakota because routes described as backups still converged on infrastructure the live call path could not bypass. Five days earlier, a different Lumen outage in South Dakota had already shown another form of…

China’s US countermeasures turn compliance into a chain of bottlenecks

Beijing’s response to new US restrictions is not one embargo. It combines case-by-case drone export review, named-company prohibitions, a change in who may inspect American factories for Chinese certification and an investigation into printing technology. The economic effect will…

Verizon's repeated 2022 911 outages showed the gap between a corrective action and a tested safeguard

A known bad update file returned to Verizon Wireless's live network after an earlier outage. The Federal Communications Commission says the December recurrence then prevented hundreds of 911 calls from completing. For a person trying to reach emergency help, the practical…

Telstra's 18,388 prepaid activations showed why a working identity check can still fall outside the authorised process

Telstra did check identity when it activated the prepaid mobile services examined by Australia's communications regulator. That fact is central to the case, because the Australian Communications and Media Authority, or ACMA, still formed the view that 18,388 activations did not…

Lycamobile's 2024 porting failures showed why providers must prove every identity check actually ran

A mobile number is easy to mistake for a line in an account record. In practice, it is a route through which calls, messages and security codes reach a person. When that number is moved to a new provider, operational control moves too. Australia's communications regulator found…

Southern Phone's 2024–2025 porting failures showed why number-transfer controls need continuous testing

A mobile number can look like a simple contact detail, but in everyday life it often works as a key. Banks send one-time codes to it. Friends, employers and service providers use it to identify the person they expect to reach. Moving that number to a new carrier therefore changes…

Optus's 2021–2023 IPND failures showed why outsourcing a data feed does not outsource accountability

A carrier can hire another company to prepare and send a regulatory data feed. It cannot hire away responsibility for the result. Australia's communications regulator found that required public-number customer information for Optus services was not supplied to the Integrated…
