There’s a lot of rampant speculation going on about Apple‘s WWDC announcements tomorrow.

The biggest question, though, may be whether or not Twitter will go down because of the traffic during Steve Jobs’ keynote.

Over the last year, Twitter has become a love/hate relationship for most users. The site has the worst uptime of all social networks, but also has some of the most passionate users.

To prepare for the onslaught, Twitter is taking some special precautions:

During the event, we are expecting approximately ten times our normal daily traffic so we’ve made some plans to accommodate this dramatic surge.

Throwing Some Weight Around

We’ve moved much of the load off our database by utilizing more memcache, employing more read-slave servers, and by fixing some bugs for improved efficiency. This work is in intended to help handle the load and keep Twitter up and running while Steve Jobs talks about all the new products and services Apple has planned. Of course these improvements will continue to serve Twitter beyond the WWDC as well.

Operation: Gray Mode

In the event that our estimates and preparations fail, we have designed a way to keep Twitter updates moving quickly through the system to their respective recipients. We have isolated and created on/off switches for many Twitter features. Should it become necessary to shed incoming load quickly, we can turn off features such as stats, pagination, and several others to preserve the reliability and timeliness of your Twitter timeline.

Sounds like a plan – but only time will tell.

There are a lot of people hoping that Twitter gets its infrastructure together – and looking for alternatives, if they don’t.
