Chase.com site is down

Wow - one of the largest banks in the world -- JP Morgan Chase -- has a website outage in the prime U.S. business hours of the day.

The company I work for is substantially smaller, but we use a Content Delivery Network (CDN) that hosts a friendly maintenance page whenever our "origin" web server farm goes down for planned maintenance or an unplanned outage.  In addition, some top-tier DNS providers also have the capability to re-route web traffic to a fail-over/DR site to maintain up-time.  Even if this is a DDoS attack, there are some technologies (including those in the aforementioned CDN) that can discard velocity attempts based on IP, geographic region, browser user-agents, etc.  If it's a botnet, well certainly then the traffic can be a lot harder to discern from legit traffic.

I'd be happy to consult with them for a tiny fraction of any lost revenue or negative dollar impact of this outage to help them improve their web architecture.  Ha!

Domain registrar pricing comparison (2014)

Registering a domain name is like trying to sign-up for and find the real cost of a cell phone plan. I couldn't find a good, unbiased and up-to-date domain price comparison (some try to funnel you to sign up for a particular registrar so they can earn a commission; I have affiliate links, but my chart is sorted by price alone!). This was pretty comprehensive, but out-of-date.   Now, this one is pretty close (Sept. 2012) , but didn't include pricing. So after personally visiting a bunch of registrar sites, I came up with the price list below. For today's post, I'm reserving comment about the quality or morality of most of these registrars, but I highly recommend doing an online search or checking a site like Better Business Bureau to make sure you're not going with a bait-and-switch type of company. These are all for a .com name, 1-year registration ignoring the introductory pricing (in other words, these are the year 2 and onward prices). These were checked...

usoclient.exe in Windows 10 wakes up my PC with Wake Source: Unknown

Image
So for a few weeks now, I've been dismissing this new Windows 10 Creators Update nag dialog. Some days I wake up to find that my PC is already awake. It turns out that Microsoft's been doing something sneaky behind the scenes. I thought I'd done all the usual methods to prevent that scenario, such as disabling the mouse from being able to wake up Windows.  Looking in Event Viewer (eventvwr), I see the wake source is Unknown. We can run a command in Windows Powershell to list all Scheduled Tasks that could wake the PC: Windows PowerShell Copyright (C) 2015 Microsoft Corporation. All rights reserved.

How to block the Admiral anti ad-block detection message

Image
I don't mind seeing the occasional banner or text ad while browsing web sites. What I do mind is malvertising, auto-playing videos (despite steps taken by browsers to stop auto-play) and excessive ads that slow down my browser to the point where it affects the user experience. This is on a modern quad-core desktop PC with 16 GB of RAM.  To that end, I gave in and installed uBlock Origin a few years ago. If ads and third-party tracking hadn't gotten so bad, I would not have had to resort to an ad-blocker. These days, sites are fighting back. They're using ad-block detection scripts in order to request that you whitelist their site. In some cases, I am happy to do this. Recently, I've seen a new one with the logo "Powered by Admiral", which pops up a modal and asks you to whitelist.  These are usually on sites that have a ton of auto-play videos and Taboola ads ("Doctors hate this one weird trick!"). I get it. Sites need ad revenue to fund thei...
