VPNs improve wifi security
Many of these mobile workers use public Wi-Fi to access corporate data, and more than one-third never use a VPN to protect their data even though two-thirds are concerned about public Wi-Fi security, according to a survey by iPass. VPN remains a viable option for securing data transferred over public Wi-Fi.
VPN risks
Are VPNs safe? Admittedly, there are security risks associated with VPNs. These include VPN hijacking, in which an unauthorized user takes over a VPN connection from a remote client; man-in-the-middle attacks, in which the attacker is able to intercept data; weak user authentication; split tunneling, in which a user is accessing an insecure Internet connection while also accessing the VPN connection to a private network; malware infection of a client machine; granting too many network access rights; and DNS leak, in which the computer uses its default DNS connection rather than the VPN’s secure DNS server.

Kurtz told NBC some users have been able to resolve the problem by rebooting their computers. But if problems persist, CrowdStrike has offered a manual workaround solution for the blue screen error. This fix involves booting the system into Safe Mode or the Windows Recovery Environment, and navigating to the C:\Windows\System32\drivers\CrowdStrike directory. Users must then delete the file title “C-00000291*.sys.” The process puts the system into a mode where CrowdStrike and other third-party drivers aren’t able to operate, according to the Verge.
WILL RESTARTING YOUR COMPUTER 15 TIMES WORK?
Microsoft said some customers using its Azure cloud were able to fix their computers by rebooting the systems as many as 15 times. Amazon also suggested rebooting computers may also solve the issue for customers using its AWS cloud software.
6 sigma quality for SMPE - Service Management Policy Effectiveness for prevention, remediation of service quality problems
6 sigma - a process being 99.9997% defect-free
Six Sigma is a set of tools and methodologies that businesses use to improve processes by reducing defects and errors, minimizing variation, and increasing quality and efficiency. The goal is to achieve a level of quality that is nearly perfect, with only 3.4 defects per million opportunities (DPMO), which is considered a "six sigma" level. This level of performance equates to a process being 99.9997% defect-free

Aggregated service quality calculations
Assume a primary service has up to 50 dependent services it invokes processing all it's apis in the contract
Every individual service is rated very high quality ( eg .999 reliability )
The aggregated quality shows the consolidated impact of 50 services that all have that quality rating
| aggregate quality | service quality | service count |
| 0.7783125571 | 0.995 | 50 |
| 0.9512056282 | 0.999 | 50 |
| 0.952157786 | 0.999 | 49 |
| 0.9426362081 | 0.99 | 1 |
the aggregated quality of consolidated services is very low
key points
- aggregated service quality is below each individual service quality
- how do we measure the service quality of each individual service
