Sorry to hear you're having problems! Can you confirm when you see this problem, and if its a continual problem or intermittent? Many thanks, Dan.

I am also having this problem with biomaRt. It seems like a hit and miss process as to whether you get a connection or not. Two days ago within the space of an hour I was getting connection some of the time and all worked as normal. But also within that hour there were many times when I just wasn't getting a connection and I was getting error messages. I was trying both the default ensembl site and the asian mirror.

I am not getting a connection now.

It looks like our Asia biomart mirror is currently down. We'll look into restarting this ASAP. Other problems may reflect excessive load on the BioMart servers, particularly by queries using very large numbers of regions or IDs. We're currently investigating how we might handle this.

It seems like there is a persistent problem with accessing the biomart service...

I saw the earlier Tweet that Ensembl servers were handling excessive queries, but I guess this situation has not changed.
