美国SK机房是一家专门提供美国抗攻击服务器的机房，国内服务商称为美国芝加哥SK机房。（2010年8月1日 SK机房-美国抗攻击服务器 丹佛数据中心启用）

国内有些不良服务器商称为ST机房，美国ST机房和芝加哥SK机房是两个不同的机房，美国抗攻击服务器，芝加哥SK机房成立于2003年，是美国唯一提供高强度ddos防护的机房，机房前期租用FDC机房资源加上自己设计的硬件防火集群建立起来的机房。美国抗攻击服务器租用，而ST机房是美国加州富尔顿的一个机房，两个机房是不同的机房，不论在价格上面还有防御方面，甚至支付方面都是不同的，美国SK机房-美国抗攻击服务器是整月式支付，没有账期。美国加州富尔顿ST机房--是一个有账期的机房，ST机房账期--每月1号。

美国SK机房--美国抗攻击机房。该机房硬件防火集群为多层防护集群，每层10G防御，总防御50G，分三层过滤。美国SK机房---美国抗DDOS机房，该机房带宽有10MB 100MB G口 甚至10G口带宽，该机房带宽资源

充足，有N家带宽提供商接入。总带宽 芝加哥SK 120G带宽接入 多家带宽提供商接入 可自由切换到国内

的线路，保持机房的稳定。SK丹佛数据中心 带宽接入30G 分别为Tinet Telia TATA等多家带宽接入。

SK机房介绍：

Sk Internet Services was established in 2003 in order to offer a complete package of high-transfer server hosting,

DDOS Filtering DDOS Filtering and Managed Services at affordable prices. Our staff members have an average of 8

years work experience in the hosting industry and our goal is to provide quality service at the lowest possible price to

our customers.

While most other companies fear services like IRC on their networks due the possibility of targeted DDOS attacks,

we support and encourage IRC usage as it is a service. Restricting services does not resolve the underlying problems,

but it temporarily hides and postpones them. Presently, DDOS is a serious threat that may occur on every internet

service.We are very proud for having developed our proprietary filtering mechanism, which allows us to reduce and fix

the cost of expensively branded filtering systems. Our proprietary filtering system gets improved on a daily basis and

mitigates DDOS attacks, preventing them from affecting our customers' servers, using numerous methods.

However, DDOS filtering (even using custom-made filtering mechanisms) requires high-end hardware equipment,

which increases the operations cost to a business. While other firms attempt to turn a profit on every service they

offer,we never have nor will charge for commodity based services. We proudly were the first hosting firm that for the

provided DDOS filtered IPs at a low price. This forced the entire market to become sensible and eliminated them from

charging thousands of dollars for a service that should remain low cost (if not free). In addition, we pioneered the

DDOS mitigation industry in regards to low-cost. We also offer one-time fee hardware upgrades (Memory / Storage) at

cost, since we mainly target long-term customers and are not trying to make a profit from upgrades.

We also were pioneers in providing dedicated servers ready for use, which included all software packages a WEB

or IRC business could need. Our focus on servicing IRC businesses includes custom OS installations with optimized

configuration and software packages that are installed by default. In addition, we also provide private access to a

shared domain list for virtual-host creation and of course the installation of our proprietary scripts that helps the our

administrators manage their servers more effectively.　SK丹佛数据中心（美国抗攻击服务器）发展历程：

SK的新丹佛机房将在美国时间8月1号开始上线

SK机房带有免费的DDOS抗攻击保护功能， 新的丹佛机房终于有了最后的上线日期。 新机房和三家带宽供

应商签署了合同，他们是TINET, TELIA和TATA。带宽目前达到30G，还在寻找第四家供应商， 以后可能会

增加。

Finally we can produce an official date we can share with our customers of the launch of our

new datacenter in Denver, CO. We have already acquired the space in the new facility and

signed up with 3 providers TINET (Formerly Tiscali), Telia, and TATA. We are also currently

looking for a 4th provider, but as of now that will give us 30Gbps of internet connection in

Denver.

新机房在建设中，计划8月1号接受新订单。

The new facility is currently under development and equipments are being purchased almost

daily. We hope to be completely in full production and accepting orders the 1st of August.

新机房将有更强壮的防攻击硬件，我们把芝加哥机房的8年防攻击经验应用到新机房。

The network infrastructure will be identical to Chicago DC and with more robust firewalls

hardware in place. We have learned from 8 years of business in Chicago and we are putting

all our experience in having a full successful launch in Denver.

We will also have a dark fiber cross-connect between Sharktech Denver and Sharktech Chicago.

This will allow cross-peering between the two facilities for outgoing traffic and inter-

network communications.

In regards to available packages in Denver there will be some different packages available

in Denver, but the highest used systems in Chicago will also be available in Denver.

美国时间2010年8月10日美国SK二大数据中心芝加哥SK数据中心和丹佛SK数据中心成功并网，此时二个数

据中心之间的ping值小于30MS。速度非常快。
