Just checked using Brave A.I.:
Red Sea Cables and Canonical Updates
There is no information in the provided context indicating that the Red Sea cable cuts affect the worldwide distribution of Canonical updates. The disruptions reported are specific to Microsoft Azure's global cloud network, primarily impacting latency and connectivity for traffic traversing the Middle East corridor, especially for Asia–Europe data flows.
The issue is related to undersea fiber-optic cables and their impact on cloud infrastructure and internet traffic, not the distribution of software updates from Canonical.
The context details that Microsoft Azure users may experience increased latency on traffic that traverses the Middle East, but traffic not using this corridor is unaffected.
While the incident has caused measurable degradation in cloud performance for cross-region operations, including database replication and backups, there is no mention of Canonical, Ubuntu, or any software update distribution system being impacted. Therefore, based on the available information, the Red Sea cable cuts do not appear to affect the worldwide distribution of Canonical updates.
The main explanation (but not what caused it) is here:

This above article mentions reverse compatibility with earlier kernels (pre-5.9) so might cause issues with terminal updates post 25.10?
