Someone "popular" on the security community on Twitter said to never host your own mail server...

Actually, do the opposite.

-Host your own mail server

-Host your own matrix homeserver

-Host your own mastodon instance

-Host your own DNS server if you can

Just do it securely and follow the good practices

Fight back on the centralization of the web.

A Criminal offered to a tesla
employee $500k to install ransomware their company network - but the employee went to the FBI.

And the criminal(s) got caught.

Amazing story:

Okie doke. Moved my URL shortener and its associated redirector domain to for DNS and monitoring.

I have a lot of faith in the guys running that and this is really the only project I have that is critical to people other than myself so it is a good candidate. (to be clear, not involved in any way).

Free 14-day trial. Give it a whirl!

It’s cool that our kids are finally of age that they can start joining our journey @dcid ... our two oldest are starting their internship with @cleanbrowsing, learning about networks, systems and business... 😊

Really happy with the way the availability and performance monitoring is working.

See how much #Linux stuff you could learn if you followed the #ManMeBot hashtag?? What are y'all even doing!

ManMeBot has posted 860 Linux commands since he was born. A fun little project I whipped up early in my Fediverse career.

Seeing a few complaints lately about:

Does anyone else find it useful?

Deciding if I should keep it running or just take it offline, if no on else finds value to look/search for accounts across instances.

Don't be shy, feedback (good or bad) is welcome!

For ISPs and telcos who have had a rubbish day because of the Equinix outage, this should probably be your evening reading.

QT decodedlegal: “Network operators: reporting obligations for reductions in availability”

A quick (but detailed) blogpost on when ISPs and telcos need to notify Ofcom because things have gone badly wrong and stopped working.

Part I of an unknown number of articles on securing your VPS to manage multiple websites.. :)

"It’s 2 am. Your phone starts to light up like a Christmas tree. PagerDuty is having a meltdown.. your slack notifications are hitting the notification thresholds.. Text messages are pouring in.. And you are sleeping.."

I will have a nightmare today after reading this horror story by @perezbox - happened a few times in the past.

Joking aside, great post showing how you can handle down times via DNS load balancing / failover.

‪Wow, China blocking HTTPS using TLS 1.3 w/ESNI because they can longer read the plain text in SNI fields. Previously used by the GFW for online censorship. What enterprise will be the first to do this?

Really good read on how the FBI caught the "twitter hacker".

Bitcoin transactions *might* appear be anonymous, but they can give out enough information & patterns to connect it to someone - specially on a high profile case (well, and bad opsec).

Does your current DNS provider gives you visibility on your DNS traffic?

This is the data for one of our small domains: dnsblacklist[.]org.

Interesting to see that Google is the #1 resolver for it.. or the traffic per hour.. or the full logs..
