Dear Sir (or Madam):
Despite the urgency of our pre-arranged schedule, I regret to say that we cannot provide our agreed requirements this evening. It appears that there is a large rally taking place in our immediate vicinity, and in the interests of safety, I am currently recommending that all our staff members return home.
We have, however, uploaded a number of pages for your review this weekend. This should include a sample of your display, content and animation requirements. In addition to these, I shall be testing the site's load time on a dial-up connection once I arrive at a secure location.
We shall resume work on Monday next week, and shall have the full site up by evening on the same day for your full review.
I apologize for any inconvenience that this may cause. Please inform me if you have any issues with the staging site so that we may resolve these on Monday as well.
