An explanation of yesterday’s widespread DNS outage and why it matters

At $WORK we lost a disk in the RAID1 of one of our external nameservers, and it rekindled an occasional discussion of migration from ISC BIND to PowerDNS. PowerDNS has separate authoritative and recursive servers, and doesn’t seem to natively support views or split-horizon the way BIND does, but …

I’m in the process of moving all of my public-facing services, currently hosted on a single Linode, to a new virtual machine (still with Linode, of course, just a new CentOS 6 VM). Of course, I’ve got a lot (about 60) of DNS records, spread across 8 domains …

Some of my servers that are only for internal/personal use have SSL certs with a mismatched hostname. The cert for my mail server is issued for the CNAME used for my mail server, not the actual hostname. Of course, this means that Thunderbird gives me some annoying errors because …

So, here’s the “official” scoop on the new project that I’m planning/starting to work on. I’m calling it PHPsa for now, and it’s going to (hopefully) be an integrated dashboard/portal for SysAdmins. While there are a number of tools that fit into this general …

Yesterday I finally began moving DNS for my sites from GoDaddy to my own in-house system of master/slave BIND9. While both DNS servers are currently at the same location and on the same WAN connection (heck, they’re beind the same router, too), so is all of the rest …

DNS is arguably one of the most important services on the Internet. Without it, every domain name and email address we know would be meaningless. We’d be thrown back into the days of IP addresses without corresponding names. And, given everything that depends on DNS, it’s also one …

In terms of ongoing projects, I should be updating RackMan sometime soon, and also adding the demo site.

I’ve begun to move DNS for all of my domains in-house, mostly because since everything is behind NAT, it’s a real pain to manage DNS entries in two places (one …

The external-facing web site and (internal use) mailing list for the ambulance corps is hosted by ROUThost. Not my choice, it was inherited. ROUThost, first off, appears to be a fly-by-night hosting provider that just buys a few boxes in a colo facility. I should have known to raise a …
