Just wanted to let everyone know that the server upgrade went well.
It is currently up and running. Feel free to submit your MTT tests as
usual.
Cheers,
Josh

Short Version:

The MTT development group is rolling out newly optimized web frontend
and backend database. As a result we will be taking down the MTT site
at IU Monday, August 27 from 8 am to Noon US eastern time.
During this time you will not be able to submit data to the MTT
database. Therefore you need to disable any runs that will report
during this time or your client will fail with unable to connect to
server messages.
This change does not affect the client configurations, so MTT users
do *not* need to update their clients at this time.

The MTT development team has been working diligently on server side
optimizations over the past few months. This work involved major
changes to the database schema, web reporter, and web submit
components of the server.
We want to roll out the new server side optimizations on Monday, Aug.
27. Given the extensive nature of the improvements the MTT server
will need to be taken down for a few hours for this upgrade to take
place. We are planning on taking down the MTT server at 8 am and
we hope to have it back by Noon US Eastern time.
MTT users that would normally submit results during this time range
will need to disable their runs, or they will see server error
messages during this outage.
This upgrade does not require any client changes, so outside of the
down time contributors need not change or upgrade their MTT
installations.
Below are a few rough performance numbers illustrating the difference
between the old and new server versions as seen by the reporter.
