                                      pretty happy with the situation. And

                                    Perhaps this metric should be
                                    changed.
                                The reasons for the failure are often
                                not site realated

                                As above

Tier-1 doing well and Tier-2's
providing good levels of service As in the previous quarter. Very happy
to high profile physics groups. generally.
