Subject Fwd: Distributed Denial of Service attack on Apache's servers today: Please be advised of changes enacted
Date Tue, 01 Sep 2015 11:09:19 GMT
Does this have an impact on DeviceMap?

As usual, please reply directly if immediate answer was required.

Otherwise could somebody please look into it, if a change is needed, it'll
affect all of DeviceMap, not just some components.

I decided to wait before proposing adjustments to the C# release. Will do
when the dust has settled over these recent issues.
It shouldn't affect a vote or preview of artifacts in a personal space.
