You can insure your place for as low as $5 per month with Lemonade

Anyone unfortunate enough to fall victim to a burglary or natural disaster understands just how frustrating it feels to deal with insurance companies.

Experiment with HTTP/3 using NGINX and quiche

Just a few weeks ago we announced the availability on our edge network of HTTP/3, the new revision of HTTP intended to improve security and performance on the Internet. Everyone can now enable HTTP/3 on their Cloudflare zone and experiment with it using Chrome Canary as well as curl, among other clients.

We have previously made available an example HTTP/3 server as part of the quiche project to allow people to experiment with the protocol, but it’s quite limited in the functionality that it offers, and was never intended to replace other general-purpose web servers.

We are now happy to announce that our implementation of HTTP/3 and QUIC can be integrated into your own installation of NGINX as well. This is made available as a patch to NGINX, that can be applied and built directly with the upstream NGINX codebase.

It’s important to note that this is not officially supported or endorsed by the NGINX project, it is just something that we, Cloudflare, want to make available to the wider community to help push adoption of QUIC and HTTP/3.

Building

The first step is to download and unpack the NGINX source code. Note that the HTTP/3 and QUIC Continue reading

Pennsylvania school district tackles network modernization

Success in business and education today starts with infrastructure modernization. In fact, my research has found that digitally-forward organizations spend more than twice what their non-digital counterparts spend on evolving their IT infrastructure. However, most of the focus from IT has been on upgrading the application and compute infrastructure with little thought given to a critical ingredient – the network. Organizations can only be as agile as the least agile component of their infrastructure, and for most companies, that’s the network.Manual processes plague network reliability Legacy networks have outlived their useful life. The existing three+ tier architecture was designed for an era when network traffic was considered “best-effort,” where there was no way to guarantee performance or reserve bandwidth, and delivered non-mission-critical applications. Employees and educators ran applications locally, and the majority of critical data resided on workstations.To read this article in full, please click here

Disaster Recovery Faking, Take Two

An anonymous (for reasons that will be obvious pretty soon) commenter left a gem on my Disaster Recovery Test Faking blog post that is way too valuable to be left hidden and unannotated.

Here’s what he did:

Once I was tasked to do a DR test before handing over the solution to the customer. To simulate the loss of a data center I suggested to physically shutdown all core switches in the active data center.
