Improving Your Singapore Subsea Cable Resiliency: AAE1 & BBG

Image
Although most subsea cables with Singapore POPs land at Singapore, some do not, and these exceptions are the keys to better uptime for your Layer 1 network. Five fibre pair AAE1 lands at a Penang, Malaysia CLS that has a fully diverse fibre ring for automatic route protection into Singapore. Each side of the fibre ring uses a separate bridge to cross the Malaysian/Singapore border. One side of the ring terminates at the older of the two Global Switch data centers and the other at SG3. So AAE1 neither lands at Singapore nor uses any of the Singapore cable landing stations. This is one reason why AAE1 is a 'must' for network capacity buyers. Other reasons include low latency for the Marseille/Singapore end points and relatively good pricing due to the system's high capacity. Bay of Bengal Gateway also lands in Penang, Malaysia, but my understanding is that it and AAE1 use different cable landing stations. However, I have not seen backhaul maps so I cannot clai...

Move Over Starlink: Blue Origin Unveils Its Plan For 6.144 Terabit Satellite Up/Down Links

Image
Blue Origin is a Jeff Bezos' startup providing space services to NASA and other clients. Those services include cargo delivery, rocket engines, lunar landing vehicles, and under development, a commercial space station. Blue Origin's New Glenn rocket carries as much cargo as SpaceX' Starship and successfully launched a NASA probe in late 2025. The first stage is reusable.  New Glenn's success has encouraged Blue Origin to develop new satellite constellations. The company announced yesterday a hybrid network of 5,280 LEO and 128 MEO satellites called Terawave that will use dual free space lasers and radio frequencies to communicate with the Earth. Radio frequency will provide a minimum committed bit rate of 144 Gibabits per second, many magnitudes greater than what Starlink offers, with free space lasers boosting the throughput by 6 terabits in ideal weather conditions. Dual connectivity is not a new idea. Low latency financial trading platforms have been using microwave ...

European Capacity Buyer Recommendations For Subsea Cable Customers

Image
Right now EUNetworks is clearly the best carrier for Layer 1 Western European network capacity. I work on a daily basis with them. The carrier offers the best combination of performance, price, and commercial flexibility. They are my default go-to provider. Note they offer wavelengths, spectrum, and metro dark fibre among other services. For ISPs they offer lower latency general bandwidth routes than their competitors. This is a big deal for African and Asian ISPs who already endure high latency to the distances between Europe and these other continents. Their new Digital Super Highways are quite attractive. These massive upgrades of the standard Western Europe routes give them a distinct edge over the 2000 era networks of their competitors. Arelion is the best transit provider, but Hurricane Electric should be a part of the upstream mix as well. RETN also has good transit. All three are in the top 15 ASN ranking which is a measure of the number of BGP links to other ISPs. These ...

An Emerging Subsea Telecom Hub: Genoa

Image
Marseille with its 16 cables tightly squeezed into reserved sea lanes and landing facilities violates the cardinal rule of network diversity. It's highly efficient, but resiliency requires physical diversity. In general, resiliency costs money because it requires not relying solely on the big interconnection points. Indeed, there is a fundamental conflict between minimizing network costs and maximizing performance. This has led consortiums and the digital titans to seek other landing points to reduce Marseille's importance. Besides being a long distance from Marseille and on a separate power grid, Genoa offers lower latency access to Italy's eyeballs as well as Switzerland, Germany, Austria, Scandinavia, and Eastern Europe. The city offers clear advantages for a landing spot.  On the down side, landing cables at Genoa is more challenging than Marseille because cables must traverse more shallow waters to reach it. Cables must be threaded between Sardinia, Corsica, and Italy....
