Denial of Service (DoS) attacks continue

It’s frustrating to have to spend time jumping off into web security and wordpress configurations when there are so many other things that are important to be doing. Today the DoS continued and the Jetpack solution didn’t seem to work. The other two solutions from Digital Ocean didn’t seem reasonable. One was to re-install wordpress with there install version. Nice that they offer a better security protected version but I didn’t feel like re-installing my (more...)

Denial of Service (DoS) attach on this site

This site had been running for a years with no big issues.
I had performance and system saturation issues about 3 years ago and then move the site to

They are inexpensive and the performance is awesome.

Then last Monday and every day since the site had been going down.

Masking with Delphix (where duplicate blocks are shared making a new copy almost free storage wise and almost instantaneous) has 4 big advantages

  1. Instant data, no copying
  2. Ease of Use
  3. Consistent across data centers and databases vendors
  4. Master/Slave

Virtual Data Masking

Delphix masking and virtualization is the most advanced solution in the market place, because Delphix doesn’t provision data. Instead of provisioning data, Delphix sets up pointers back to existing data for a new clone. When that (more...)

Delphix Replication

Someone just asked on the Delphix Forums whether they could test Delphix replication with the free version of Delphix called Delphix Express.

I’d never tried, so I sat down to try and was amazed at how easy it was.

I created twoDelphix Express installations.

On one engine, the source engine, (  I linked to an Oracle database on Solaris Sparc called “yesky”.

On that same engine I (more...)
