Due to changes in the networking infra-structure and special requirements for the imminent release of the 3D rework of the "Big Buck Bunny" movie the usual Monday maintenance window will be extended to start close to midnight between Sunday and Monday the 16th(00:00 UTC) and extend into Tuesday night.
During this time there will be times of limited connectivity and quite likely the website will be very slow or not function properly at all. This also counts for the BOINC-related backend features.

Afterwards, at some point during this week, the BBB3D release will be made from a set of hosts in the same server cluster that hosts BURP and a number of other projects. I apologize in advance if the BURP site becomes very slow or even completely unreachable due to overload.
A small warning (since we don't usually apply highly aggressive traffic control rules):
If things are slow or you receive "Service Unavailable" or similar error messages please do not repeatedly hit "Refresh" on the website or "Update" in the client. The server is trying to handle incoming requests in the order that they are made, hitting update will put you right back at the end of the queue. If you DO hit "Refresh" a lot, you are likely to be marked as a Bad Person™ - and the server cluster will no longer talk to you at all.
The hope is that things will be back to normal around next weekend.

Sounds like a job for the BURP mirror network :P

Heh yeah, except it isn't the actual downloads that are scary - most of those will be handled off-site or via BitTorrent - it is the potential number of concurrent connections from visits to the release mini-site and new visitors to BURP that has me worried a bit. For the same reason, the mini site is entirely static html5 to avoid having load propagate to the backend servers.

It is going to be interesting to see how the setup handles flash crowds. On the other hand, maybe no-one is interested in BBB3D and this is all an exercise in futility =)

Turns out that the traffic hasn't been decreasing - in fact it is still increasing over the weekend as more and more news sites pick up the news - luckily the server seems to be doing just fine. Due to the unusual load on the server, and the fact that I'm also taking a bit of a holiday vacation with family and friends, please do not expect too much to be happening on BURP over the next few weeks.

Merry Xmas - and a happy new year to all of you!
