Facebook Explains Backbone Shutdown behind Global Outage

The massive outage that took down Facebook, its associated services (Instagram, WhatsApp, Oculus, Messenger), its platform for businesses, and the company’s own internal network all started with routine maintenance.

According to Santosh Janardhan, infrastructure vice president, a command issued during maintenance inadvertently caused a shutdown of the backbone that connects all of Facebook’s data centers, everywhere in the world.
That by itself is bad enough, but as we’ve already explained, the reason you couldn’t use Facebook is that the DNS and BGP routing information pointing to its servers suddenly disappeared.
According to Janardhan, that problem was a secondary issue, as Facebook’s DNS servers noted the loss of connection to the backbone and stopped advertising the BGP routing information that helps every computer on the internet find its servers.
The DNS servers were still working, but they were unreachable.
Yesterday’s outage across our products was a bad one, so we’re sharing some more detail here on exactly what happened, how it happened, and what we’re learning from it: https://t.co/IXRt572h4c

The lack of network connections and loss of DNS cut off the servers from engineers trying to fix the issue and disabled many of the tools they normally use for repair and communication — just as we heard yesterday.
The blog post notes that the engineers had additional hurdles due to the physical and system security around this crucial hardware. Once they did “activate the secure access protocols” (this is apparently not a code word for “cut open the server door with an angle grinder), they were able to get the backbone online and slowly restore services in gradually increasing loads. That’s part of the reason it took some people longer to get access back yesterday, as the power and computing demands of turning everything on at once might have caused more crashes.
So that’s it. No conspiracy theories, and no techs taking axes to secure facilities to turn Mark Zuckerberg’s baby back on. Just a bug in a command that an audit tool missed, and for six hours, services that connect billions of people disappeared.

IFC Invests $45m to Green African Telecom Sites

Clean and reliable power for telecom networks in Ethiopia, Liberia, and Sierra Leone will be expanded following a $45 million investment by the International Finance Corporation (IFC) in IPT PowerTech.

The investment targets countries where limited power supply continues to slow digital connectivity and broader economic participation, the institution stated earlier this week.
To enable this expansion, the IFC is providing a $45 million corporate financing package consisting of an A-loan of $27 million and $18 million in blended finance.
The blended portion is sourced from the Canada-IFC Blended Climate Finance Programme and the IDA20 Private Sector Window Blended Finance Facility.
The initiative marks the IFC’s first direct infrastructure engagement in Liberia in a decade and in Sierra Leone in six years.
It will help scale solar- and battery-based power systems that reduce reliance on diesel and support greener, more resilient telecom networks.
By improving the quality and stability of power to telecom towers, the initiative will strengthen mobile coverage and ensure that households, schools, health centres, and small businesses can depend on consistent digital services, said the IFC.
The funding supports the modernisation, operation, and maintenance of 2 235 telecom sites across the three nations. More than 90% of these are located in off-grid or weak-grid locations.
With new solar and battery systems powering these sites, mobile networks will experience fewer outages and improved service quality.
Optimising the energy mix is estimated to reduce power costs for operators by up to 30% in Liberia, 26% in Sierra Leone, and 52% in Ethiopia.
This transition is also expected to cut emissions by more than 10 624 tonnes of carbon dioxide annually. Furthermore, the partnership will promote gender inclusion by expanding opportunities for women in technical, operational, and leadership roles within the sector, says the IFC.
This agreement reflects a shared vision for a greener telecom industry and empowers the company to scale its innovative energy platforms, according to Nabil Haddad, CEO of IPT PowerTech Group.
Reliable and affordable power for telecom networks is a cornerstone of Africa’s digital transformation, said Nathalie Kouassi-Akon, IFC regional director for West Africa and the Gulf of Guinea.
Through this partnership, the institution is supporting a scalable, private sector-led solution that enables mobile operators to reach underserved and fragile communities more sustainably, added Kouassi-Akon.
The project advances the World Bank Group and African Development Bank’s Mission 300 initiative, which aims to provide electricity to 300 million Africans by 2030.

NCC Launches Platform for Secure Mobile Numbers, Anti-Fraud

Nigerian Communications Commission (NCC) has launched the Telecoms Identity Risk Management System (TIRMS) to enhance digital security and fight telecom fraud.

NCC
Dr Aminu Maida, Executive Vice Chairman, represented by Executive Commissioner Rimini Makama at an Abuja stakeholders’ forum, stressed mobile numbers (MSISDNs) as vital for banking, authentication, and services—but vulnerable to misuse via recycled, churned, or barred SIMs.
“The TIRMS Platform is a secure, regulatory-backed, cross-sectoral solution… to provide a uniform approach for managing risks relating to the integrity and utilisation of registered MSISDNs,” Maida said.
Objectives include better MSISDN access for accountability, fraud checks on dormant/suspicious numbers before service access, and proactive verification across sectors.
Proposed rules mandate 14-day churn notices, seven-day data submission to TIRMS, and blocking of fraudulent lines. Success hinges on telecoms, banks, security agencies, and others.
Maida highlighted NCC’s collaborative rulemaking for a “One Government” approach.
Cybersecurity Director Olatokunbo Oyeleye called digital trust an “operating licence” for growth: “Every mobile number in Nigeria [must] be trusted… TIRMS will safeguard users, reduce fraud, and reinforce confidence in our digital economy.”
TIRMS bridges gaps with CBN, NIMC, CAC, SEC, and PENCOM, aiming to cut fraud and boost trust.
