Bandwidth Alliance Partners – Exciting Choices
We are tremendously excited about the value our Bandwidth Alliance partner ecosystem adds to our customers. We’re on a mission to help make the internet a better place; and ensuring everyone can access cloud resources at zero-egress rates supports that mission in many ways. It’s an easy way for our clients to build modern, cloud-centric applications without the design constraint and financial burden of egress fees.
The cloudflare bandwidth alliance partner landscape continues to grow, and incorporate a diverse group of partners, with today’s second wave announcement. With over a dozen different partners, the range of choices can quickly become overwhelming. And, while these are all high-quality platforms which we are happy to recommend to our clients - their important differences will help determine the best fit for you, the customer.
In this post, I’ll lay out some of Cloudflare’s approach to this solution design question through the lens of a large client we recently worked with. We apply this approach across our full range of products and services, including many use cases far different from the Storage need we’ll dig into in this post. I hope that this can help all of our clients, or anyone else interested, mirror Continue reading
Expanding the Bandwidth Alliance: sharing the benefits of interconnected networks
At Cloudflare, our mission is to help build a better Internet. That means making the Internet faster, smarter, safer, but also more cost efficient with the help of our partners. We are always on the lookout for ways to help save customers money. With that goal we announced the Bandwidth Alliance with our founding partners during our Birthday week.
The key concept of the Bandwidth Alliance is to help reduce and in many cases waive data transfer charges, sometimes known as "bandwidth” or “egress” charges, for our mutual customers. We achieve this in partnership with the founding partners through strongly interconnected networks over peered connections. These connections typically occur within the same facility with no middleman. So, neither Cloudflare nor the cloud provider bears incremental costs. Further, we will also use our smart routing system (read details in this technical blog post) to ensure that all our customers’ traffic on participating cloud providers, once their systems are set up, qualify for this offer.
Expanding the Alliance: new Partners Committed to Discounting Data Transfer Fees
We are proud to announce the following cloud providers and hosting companies have joined the Bandwidth Alliance in committing to zero data transfer fees for Continue reading
Route Leak Causes Major Google Outage
Google recently faced a major outage in many parts of the world thanks to a BGP leak. This incident that was caused by a Nigerian ISP – Mainone – occurred on 12 November 2018 between 21.10 and 22.35 UTC, and was identified in tweets from the BGP monitoring service BGPMon, as well as the network monitoring provider Thousand Eyes.
Google also announced the problem through their status page:
We’ve received a report of an issue with Google Cloud Networking as of Monday, 2018-11-12 14:16 US/Pacific. We have reports of Google Cloud IP addresses being erroneously advertised by internet service providers other than Google. We will provide more information by Monday, 2018-11-12 15:00 US/Pacific.
In order to understand this issue, MainOne Inc (AS37282) is peering at IXPN (Internet Exchange Point of Nigeria) in Lagos where Google (AS151169) and China Telecom (AS4809) are also members.
Google (AS15169) advertise their prefixes (more than 500) through the IXPN Route Server, where PCH (Packet Clearing House) collects a daily snapshot of BGP announcements of IXPN. Unfortunately, 212 prefixes (aggregates of those 500+ announcements) from Google were leaked, which was recorded by BGPMon and RIPEstat.
Looking at the RIPE stats it is evident Continue reading

How a Nigerian ISP Accidentally Knocked Google Offline
Last Monday evening — 12 November 2018 — Google and a number of other services experienced a 74 minute outage. It’s not the first time this has happened; and while there might be a temptation to assume that bad actors are at work, incidents like this only serve to demonstrate just how much frailty is involved in how packets get from one point on the Internet to another.
Our logs show that at 21:12 UTC on Monday, a Nigerian ISP, MainOne, accidentally misconfigured part of their network causing a "route leak". This resulted in Google and a number of other networks being routed over unusual network paths. Incidents like this actually happen quite frequently, but in this case, the traffic flows generated by Google users were so great that they overwhelmed the intermediary networks — resulting in numerous services (but predominantly Google) unreachable.
You might be surprised to learn that an error by an ISP somewhere in the world could result in Google and other services going offline. This blog post explains how that can happen and what the Internet community is doing to try to fix this fragility.

Mininet, ONOS, and segment routing
This article will describe how to emulate a leaf and spine network using Mininet and configure the ONOS segment routing application to provide equal cost multi-path (ECMP) routing of flows across the fabric. The Mininet Dashboard application running on the sFlow-RT real-time analytics platform is used to provide visibility into traffic flows across the emulated network.
First, run ONOS using Docker:
docker run --name onos --rm -p 6653:6653 -p 8181:8181 -d onosproject/onosUse the graphical interface, http://onos:8181, to enable the OpenFlow Provider Suite, Network Config Host Provider, Network Config Link Provider, and Segment Routing applications. The screen shot above shows the resulting set of enabled services.
Next, install sFlow-RT and the Mininet Dashboard application on host with Mininet:
wget https://inmon.com/products/sFlow-RT/sflow-rt.tar.gzStart sFlow-RT:
tar -xvzf sflow-rt.tar.gz
./sflow-rt/get-app.sh sflow-rt mininet-dashboard
./sflow-rt/start.shDownload the sr.py script:
wget https://raw.githubusercontent.com/sflow-rt/onos-sr/master/sr.pyStart Mininet:
sudo env ONOS=10.0.0.73 mn --custom sr.py,sflow-rt/extras/sflow.py \
