Cloudflare’s network currently spans more than 330 cities in over 125 countries, and we interconnect with over 13,000 network providers in order to provide a broad range of services to millions of customers. The breadth of both our network and our customer base provides us with a unique perspective on Internet resilience, enabling us to observe the impact of Internet disruptions at both a local and national level, as well as at a network level.
As we have noted in the past, this post is intended as a summary overview of observed and confirmed disruptions, and is not an exhaustive or complete list of issues that have occurred during the quarter. A larger list of detected traffic anomalies is available in the Cloudflare Radar Outage Center. Note that both bytes-based and request-based traffic graphs are used within the post to illustrate the impact of the observed disruptions — the choice of metric was generally made based on which better illustrated the impact of the disruption.
In our Q1 2025 summary post, we noted that we had not observed any government-directed Internet shutdowns during the quarter. Unfortunately, that forward progress was short-lived — in the second quarter of 2025, we Continue reading
Momentum is building for quantum computing and some observers say that a usable, fault-tolerant quantum system could appear in the next few years. …

A while ago, I published a blog post proudly describing the netlab integration test that should check for incorrect OSPF network types in netlab-generated device configurations. Almost immediately, Erik Auerswald pointed out that my test wouldn’t detect that error (it might detect other errors, though) as the OSPF network adjacency is always established even when the adjacent routers have mismatching OSPF network types.
I made one of the oldest testing mistakes: I checked whether my test would work under the correct conditions but not whether it would detect an incorrect condition.
Recently, I started self-hosting most of the apps I use, like Memos for note-taking and Paperless-NGX for document management. The next one on the list was Immich. Immich is a self-hosted photo and video backup solution that supports features like facial recognition and automatic uploads.

In this post, we’ll look at how to set up Immich as a Docker container and also how to add an NFS share as an external library.
I have a lot of pictures on my NAS that I’ve collected over the years. This includes photos of friends, family, and ones from my older phones. I wanted a way to manage and organise them from one place. I also didn’t want to upload all of them to Google or Apple, which would cost quite a bit. Continue reading

Writing tests that check the correctness of network device configurations is hard (overview, more details). It’s also an interesting exercise in getting the timing just right:
And just when you think you nailed it, you encounter a device that blows your assumptions out of the water.
What is DNS Delegation and what is it used for? What is new in the Delegation world, and what impact does it have on DNS security and operations? George Michaelson joins Tom Ammon and Russ White for a discussion about DNS DELEG in this episode of the Hedge.
InfiniBand was always supposed to be a mainstream fabric to be used across PCs, servers, storage, and networks, but the effort collapsed and the remains of the InfiniBand effort found a second life at the turn of the millennium as a high performance, low latency interconnect for supercomputers running simulations and models. …

Cloudflare has servers in 330 cities spread across 125+ countries. All of these servers run Quicksilver, which is a key-value database that contains important configuration information for many of our services, and is queried for all requests that hit the Cloudflare network.
Because it is used while handling requests, Quicksilver is designed to be very fast; it currently responds to 90% of requests in less than 1 ms and 99.9% of requests in less than 7 ms. Most requests are only for a few keys, but some are for hundreds or even more keys.
Quicksilver currently contains over five billion key-value pairs with a combined size of 1.6 TB, and it serves over three billion keys per second, worldwide. Keeping Quicksilver fast provides some unique challenges, given that our dataset is always growing, and new use cases are added regularly.
Quicksilver used to store all key-values on all servers everywhere, but there is obviously a limit to how much disk space can be used on every single server. For instance, the more disk space used by Quicksilver, the less disk space is left for content caching. Also, with each added server that contains a particular Continue reading
