Submarine Cable Maps 2013-2019 Hi, Each year Telegeography makes some awesome submarine cable maps. They’ve been doing this for some time now, and the versions for year 2013 through 2019 is available here; 2013 2014 2015 2016 2017 2018 2019 During the last few years, I’ve stitched these together as high resolution pictures (.png).

Python for Network Engineers course starts on next Tuesday, Sept 3rd (free course)

Python for Network Engineers course starts on next Tuesday, Sept 3rd (free course) We periodically run a free course on Python for Network Engineers (about once a quarter) and that time has come again…so we will be running this course again starting on Tuesday, Sept 3rd. The course is fundamentally about Python, but told with a network engineer’s bent (i.e. the examples and exercises are more relevant to network engineers). Later in the course we also get into some more networking specific topics (Netmiko and Jinja2 for configuration templating). The…

Longest Network Connection in the Universe?

Longest Network Connection in the Universe? Every once in a while I go onto the Deep Space Network site to check on Voyager 1 and 2, and just to see what’s going on in general. Currently the round-trip time to V1 is about 1.69 days with a data rate of 150 bits/second, although I’ve seen it as low as 6 bits/sec. V2 is a bit closer at a mere 11 billion miles or so. It’s amazing to me that the entire space craft runs on 4 Watts. V1 and 2…

hyperglass: a python looking glass for making the internet suck less

hyperglass: a python looking glass for making the internet suck less Once upon a time, I was helping a customer troubleshoot some connectivity issues to my employer’s cloud services. I was logging into looking glass servers for every tier 1 carrier in the path and getting frustrated that the little tier 2/3 shops didn’t have their own looking glasses for me to use, forcing me to make educated guesses about how traffic being routed within their network. Then I started to look inward, and thought to myself, “well, why don’t…

Is it normal to leave work brain dead everyday when in IT?

Is it normal to leave work brain dead everyday when in IT? Network Admin here. Kind of a silly post, kinda not. Ive been working in IT, mostly Networking, for 4 years now. It’s not hard to notice that it’s a very mentally taxing field. As of probably the last year maybe year and a half, I feel like I leave work everyday just completely mentally drained. I can’t focus on much after work, and by the time I get relaxed on the weekend, it’s Monday again. I don’t feel…

[UPDATE] I shut down my company over thanksgiving to do a network migration and somehow it all worked.

[UPDATE] I shut down my company over thanksgiving to do a network migration and somehow it all worked. I’m baffled as to the how and why, but it’s all back up. Interestingly, when I got to the office at ~8am on Thanksgiving day my first couple hours were spent dealing with a problem of actual tubes instead of metaphorical tubes. Our fizzy water machine had decided to start leaking sometime in the middle of the night. If I hadn’t been doing this work today, no one would have see this…
