Devolo dLAN Homeplug Networking
I live in a pretty typical for London double story house, my study is upstairs with TV etc downstairs. Till now I just use a Wireless N router to get connectivity downstairs but it's proven to be less than reliable. Additionally my ADSL router was upstairs - but on an extension and not on the main plug, it's a recipe for disaster.
I've considered many options, long cables and all sorts of things like this. Today while wandering through PC shops trying to find a decent USB reader I again noticed the Homeplug devices and thought I'll give them a try.
I bought 3 units of the Devolo dLAN 200 AVeasy units, they are 200Mbps maximum devices and support all sorts of fancy things like AES Encryption and basically an ACL of sorts to only allow certain devices to talk to each other. You can essentially create a VLAN by giving groups of devices different passwords etc.
At first I was fairly sceptical but figured it's worth a shot, I am glad to say the devices totally exceeded my wildest expectations.
Installation was a breeze, pop them into the wall, plug in cables and it all just work. Of course it is not secured by default so I went digging through their site, the docs and so forth is pretty crap to say the least but I found software for Linux, Windows and OS X to manage them. Each device has a security id on the back and you just type the keys for all your devices into the app and provide a password. This gets used to secure the network with AES.
I have now moved my router and firewall machine downstairs to the main socket - ADSL is now much stabler - and have moved the Wifi router downstairs too via the Devolo units. Overall the whole setup just works great, even my Xbox is working great again after my old Wireless Bridge died.
I use a 1GB switch on my LAN and get around 0.3ms ping times in general, if I ping a device on the other end of the Devolo units ping times are around 4ms, transfer speeds over the units are around 7MB/sec when using scp, these figures are very respectable and much better than I had hoped for in the past while considering them.
At +- 50 GBP per unit and the sacrifice of a wall socket its a pretty expensive solution (other manufacturers apparently have ones that act as a network and power adapter so you don't waste a port) but for me this has proven to be an excellent solution and completely sorted out my network reliability issues.
Layeredtech’s thanks to old customers
I have been a customer of Layeredtech for years, at present I have only 2 machines there but at times I've had 7 or 8. My one machine is pretty old, I think I got it circa 2002 or so and it's been doing well, same hardware etc.
Yesterday I received the following email from them:
Layered Tech is committed to being the leader of the Hosted
Infrastructure market by providing our customers with the best products
backed by the best service. In an effort to improve our customer
experience, we have determined that a small number of existing servers
will need to be relocated from their current data center. As you are
receiving this message, we have identified that you have one or more
servers in the in area of the Savvis facility that will need to be
moved. It is our intention to minimize any interruption in service and
we will do our best to work within predetermined time frames that are
convenient to you.Due to the form factor (chassis type) of
this server, we will need to migrate your data to a new server. We will
work with you so that the impact is as minimal as possible.Below
are the servers that are affected by this migration. Please respond to
this message acknowledging the need to relocate your server(s). At
that point, we will move this ticket to our Operations Department where
we will work with you on a migration schedule.
From reading this you might assume they will assist you with the migrate and this is a notice of an impending change, perhaps a month or two from now?
In reality the situation is that no, they will not help you migrate your data. They want you to take out a contract for a new machine and then migrate your data yourself - something which even at best will take 5 to 10 hours on oldish machines like this.
They do not offer any compensation, and when pressed on that point only offer 1 month...the cherry on the cake is that all this has to be done for 18 days from now, in effect they are terminating your old machine forcing you to take a new one and doing it with less than the agreed 30 days notice. Like it or not.
The sales person who has been coordinating this from their side is incredibly unhelpful and frankly useless, only after much pushing back by me do I even get a hint that anything other than do-it-yourself migration is an option, at this point still waiting for details.
This kind of disregard for customers is typical of large hosting centres, they have thousands of customers and their hard handed handling of their customers is acceptable because at worse they'll loose a fraction of a percentage of customers, so being unhelpful really does pay off for them since most people will probably just take this crap.
This is shockingly poor service, if you value your data, avoid Layeredtech.
