pre-payment discounts

| | Comments (0)
Hey, so dealing with payments is something of a pain. It's easier if you send me fewer, larger payments. So to encourage this behavior, I am offering some discounts:

  • pay for 3 months, take 5% off
  • pay for 6 months, take 10% off
  • pay for 12 months, take 20% off

right now there is no minimum cheque size, but once I get Paypal hooked into freeside to automatically input payments, I will institute a minimum cheque size. (until I automate the paypal stuff, it doesn't really matter... right now, both mean that I have to manually input the payment)

I'm moving all the prgmr.com servers at he.net into one rack. Irritating, I know, but it makes server management much easer, and I'll have more control over the network.

Unless I screw up the dhcp server (like I did last time) you should not notice anything more than being unreachable for 30 minutes. The server should automatically save and then restore your domain, with all programs running. If you get rebooted, I screwed something up.

rdns for 216.218.210.65/27 fixed

I had a messed up $ORGIN statement, so rdns has never been working on those addresses.  It's  working now

has anyone experience with SVTIX?

So, I need more co-lo space. I'm currently at he.net. They are OK, I guess. My international customers seem to be pretty impressed with my latency, and I like the native IPv6.

The problem is that they will only sell you 15A circuts (that's only 1125 watts usable. A competent admin is never going to go above 75% of a circuit's rated capacity, so we are talking fitting 9 or 10 of my 1U servers in that full rack.) at the freemont location where I am, and they were full last time I asked anyhow.

I need 20A of power (if I can get 30A single-phase 208V, that's even better) a full (locking, 4 post) cabinet, and a 10Mbps commit on a 100Mbps pipe (bonus if it's a 1000Mbps pipe) with reasonable overage charges. I also want the ability to bring in cross connects from other providers and exchange points as my bandwidth use grows.

(now, no two ways about it. He.net is a cheap provider. you can hear the whine of the alarms on the failed PDUs as you walk through the place. But unless your hardware is a lot better than mine, even a crappy datacenter is going to be a whole lot more reliable than x86 hardware. I like cheap.)

So I've been looking around. I found some ridiculously good prices at egihosting for 20A circuits, and very fair bandwidth prices. they are in at SVTIX in san jose. the big problem here is that they don't allow cross connects from other providers (which in my experience means that once they have you locked in, they will screw you on bandwidth charges.)

I'm asking SVTIX for a direct quote, we'll see what they have to say. If any of you have used them, let me know what you thought.

But yeah. I want to play with BGP and peering... this means I need access to cheap bandwidth so I can get my usage up to something worth peering with without breaking my budget, and I need to get access to more than one provider, and once my usage is up, I need to get access to something like metroPAIX or some other major exchange.

No, I've not setup non-PAE servers, but NetBSD-CURRENT has supported x86_64 and i386-PAE (as a DomU only)  for some time now. I just go around to testing and setting it up. 

full instructions here: http://book.xen.prgmr.com/mediawiki/index.php/NetBSD_as_a_DomU

or if you are a new customer, I've included the NetBSD install kernel in the menu.lst in all my debian x86_64 images. 

It looks to work (though it is still -current)  -  It hasn't crashed on me yet. 


rebooting hydra and lion

if I do it right, all you will notice is 5 minutes of inactivity, as Xen is configured to save all the DomUs to disk.  (much like how you can  hibernate your laptop)

In the spirit of "only make each mistake once" we are installing serial consoles after the problem on boar the other day.   We will also be upgrading dom0 kernels to the centos latest.

more unplanned downtime.

Or, wouldn't remote console access be nice?

Boar.prgmr.com appears to be down.  We're bringing it back up as soon as possible.  Here's the back story:

I stupidly created two domUs with identical MAC addresses.  As far as we can tell, this destroyed Xen's virtual bridge. . .  First my SSH connection went.  Twenty minutes later, the entire box and domains hosted on it became unpingable.  I feel terrible about the entire thing.

Luke's headed out now to reboot the machine.

I think I'm going to write some Python to automatically generate MAC addresses from IP addresses.
