What Occurred:
- On [14 March 2024] at approximately 12:50, cable breaks led to a significant 40% increase in international traffic as data was rerouted from local Peering Exchanges.
What we did:
Our BGP optimization application identified congested paths and automatically re-engineered and balanced traffic across international links to mitigate the issue.
- Our network has been managing the additional traffic, and we took immediate action to re-engineer and balance traffic across our international links. However, some international paths reached capacity and we started experiencing packet drops at 19:45 (14 March), prompting us to begin rerouting traffic to alleviate congestion and packet drops. Packet drops cleared at 20:50 following traffic re-engineering/balancing and optimization.
What to Expect:
Repairing undersea cables can be a lengthy process, often taking a month or more. We anticipate that hyperscalers will be securing more capacities to improve their situation in the coming days.
BGP Optimization and Support:
Our BGP optimization application continuously analyses traffic patterns and adjusts routing protocols (BGP) for optimal performance. This system can also optimize specific IP addresses (VIPs) upon request. If you experience service degradation or require VIP optimization, please log a support ticket at support@networkplatforms.co.za. We do have standard rules for major cloud and gaming environments already .
Repair Updates:
- There is currently no ETA issued regarding the undersea cable repairs. We will update customers as soon as we have more information.
We appreciate your understanding and patience during this time. Our team is dedicated to ensuring the optimal performance of our network and will continue to monitor closely, making adjustments as necessary.
Further updates will be provided as more information becomes available.
Thank you for your continued support.
