Quick Quote

Apropos of nothing, I just ran across this quote:

Plato used the dialogue format because the exchange of views, the posing and answering of questions, showed that understanding is a living, dynamic process. He distrusted writing because the settled character of the written word makes it look as if truth can be fixed and made to stand still. It is worth remembering that this greatest advocate of the objective reality of truth also believed that our access to that truth was sustained in reasoned discussion.

— John Churchill, From the Secretary: Inspiring Conversations in The Key Reporter. Vol 67, Number 4. P. 2., Summer 2002

I think this is one of the strongest, most concise arguments in favor of free speech and open debate that I have ever heard. I’d never heard of this guy, but it seems he’s the secretary of Phi Beta Kappa. Sounds like a smart cookie.

(Posted at the very lowest possible priority on our blog because it doesn’t have anything to do anything, bears repeating, and won’t fit in a tweet.)

Scheduled maintenance November 22 and December 15

We are scheduling two maintenance windows in the next month to move some equipment:

Date: November 22nd, 2010
Window: 9am to noon UTC (4am to 7am US Eastern, 1am to 4am US Pacific)
Affecting: MySQL nodes m2, m3, and m21

Date: December 15th, 2010
Window: 8am to 1pm UTC (3am to 8am US Eastern, midnight to 5am US Pacific)
Affecting: File servers f2 and f5

Each server should be offline for about one hour, not the whole window. This will cause some downtime. While the MySQL nodes are offline, those MySQL processes hosted on them will be unreachable. While the file servers are offline, sites hosted by those file servers will show an official maintenance page.

Removing deprecated IP block

Many years ago, we were assigned the IP address block 64.238.220.0/23 by one of our upstream network providers. We officially deprecated the use of that block way back in 2008, and we will be returning it on December 1st, 2010, so it will not work after that point.

Brief Network Maintenance July 20-22

This is just a quick announcement about some upcoming network maintenance.

Due to our load-balancing capabilities, most of this will be done with no disruption to our services. There are a few exceptions, though. We’ll be doing maintenance over the next few days in the early morning hours (between 1am and 5am US Eastern time — 5am and 9am UTC), the following services will be briefly disrupted (should be about 5-10 minutes each):

Domain registration price increases

Verisign has pricing increases going into effect on July 1st. As a result of these pricing changes, our registrar partner has informed us of corresponding increases which we must, in turn, pass along.

Effective July 1st, the new price for domain registrations, renewals, and transfers will increase from $8.59/year to $8.99/year.

Get your domain renewals in now to avoid the increase.

These changes have nothing to do with us, are not under our control, and are of no benefit to us. They’re bad for us, and they’re bad for you. Unfortunately, the same (auto-renewing into perpetuity) contracts with ICANN that grant Verisign a monopoly over .COM, .NET, and .NAME domains (among others) enshrine Verisign’s right to unilaterally raise prices by 7% every year, and they never miss a chance to do so. Their 30% profit margin in 2009 will almost certainly increase after they finish unloading everything not domain-related onto Symantec. It’s not bad work if you can get it. (And live with yourself afterward.)

Pools: Arbitrary HTTP Servers, Resource Reservation and Scalability

We are pleased to announce that we are beginning the beta of our new “pools” service. Pools are a way to reserve memory and CPU power for one or more web sites. This approach makes it possible to discard many of the limitations traditionally associated with our service.

A RespectMyPrivacy discount, a few UI upgrades, and Twitter?

We’ve released a minor update to our member UI with a few new features, one of which is of particular note: a 10% discount on RespectMyPrivacy service is now available in exchange for prepayment.

File server “f1” replacement

Our venerable old file server “f1” had some problems last month that left us with some doubt as to the viability of its redundant power supplies over the long term. Since then, we’ve been planning and preparing to migrate all the sites it handles to other, newer file servers.

That’s all been prepped now, and what we’re going to do is automatically migrate everyone during the month of April. If you have affected sites, you can get a specific time for each site from our member interface, and the main sites page will star any site scheduled for an upgrade on your list of sites so you can see at a glance which sites are affected.

Scheduled Downtime for Friday, November 20

We have some facilities maintenance scheduled for this Friday. As part of this maintenance, we will need to physically move a handful of critical file and database servers between racks in our Phoenix datacenter. Since that equipment forms the heart of our hosting service, we’ll need to shut almost everything down briefly, just long enough to move it.

The maintenance window will be from 10am to 4pm MST (5pm to 11pm UTC) on Friday, November 20th, 2009.

A PHP Include Exploit Explained

We are having a fairly consistent problem with spammers auto-exploiting a very common type of scripting vulnerability that appears on our members’ sites. Unlike most vulnerabilities that stem from a faulty version of some app a lot of people use, this one crops up primarily on sites containing PHP code that people write themselves.

Cleaning up the resulting messes is getting a little tedious and so, even though this is hardly a new exploit, I wanted to write a little bit about what the vulnerability is, how it works, how spammers exploit it, and how to keep your site safe.
