To moonfaery_87 and daveisnotmyname, as far as things getting lost, it doesn't appear to be what is going on. What appears is that access to the biometric data is inaccessible the vast majority of the time. At this point it doesn't appear that anyone will have to have biometric appointments again.
What this really means is that almost all visas that have been submitted over the past week or so are likely on hold or being processed at a snails pace and there is no clear resolution time at this point.
What can you do? Well, one thing you cannot do is show up at your consulate and start yelling. The best course of action is to continue to voice here or somewhere that you are being affected by this. A whole slew of people are watching this now, including UKBA themselves. Because of the way this was approached it may have been that some mid-level folks were trying to keep this quite and just felt it was teething problems, but now it is getting out of hand. The ILPA, which is the largest group of people practice immigration law in the UK, are hopping mad at this, in particular because they hadn't been told it was going on. So be confident that people are working on your side on this one.
If you really feel you need to take action, your UK sponsor can e-mail their local MP
http://www.theyworkforyou.com/ and suggest to their MP to make representations on their behalf to the Right Honourable Mrs Jacui Smith or the Right Honourable Mr Phil Woolas about the situation and the problems it is causing you.
If you need to vent your frustration, vent it here. Taking this out directly on anyone you have contact with at a courier, government contractor or UKBA probablly will only make everyone more frustrated and not resolve anything.
