I know exactly where you are coming from ! 
Yesterday afternoon, after 180 days uptime, I powered down my pfSense box to replace a noisy fan and install some fan speed reducers, blew the box clean with compressed air, upgraded the wireless adaptor, refitted the router, updated pfSense to the latest (v2.1.5), and upgraded the installed packages (including Squid3 caching proxy) to the newest revisions.
Back online in less than an hour while the family were out for the afternoon - so the house was quiet for listening to reduced fan speeds, and no other demands on the internet. I was pleased to have successfully got several jobs done in one go, and looked forward to attempting to exceed another 180 days uptime before anything else needed doing to it.
Then exactly four hours later (at 18:00), I received the email from pfSense to say that the major revision v2.2 had just been released.

But... is something wrong with my connection tonight or are those mirrors crawling? I can't wait that long to download 84mb!
Try again tomorrow.
Yes the UK mirrors do seem slow at the moment. 
I'm currently seeing 70KB/s which is approximately 21 minutes to download the .iso file.
I've never seen it that slow before, normally upgrades and full downloads take just a few minutes.
I'm not surprised though, as this release is a massive improvement on the 2.1.x versions,
and will be a popular upgrade which a lot of people have been waiting a long time for.

Tonight, download speeds from the pfSense UK mirrors is MUCH FASTER (than yesterday),
I'm currently getting about 760KB/s, which is about as fast as my congested exchange and 20CN ADSL line can provide.
