Interesting..the exact words used at approx. 620am local DXB, were:
"All aircraft holding at Bubin, standby for new EAT's because the arrivals managers computer at DXB is unable to keep up with the volume of arrivals and has failed"
The next communication was a readout of new EAT's in excess of 1 hour later that the previous EAT's. This was communicated from UAE..not DXB arrivals.
