[dhi-servers] Isilon service restored - IRIS_DataCenter restored

[Charles Ammon]

Hi Chris,

Thanks. I can wait until things are worked out with the missing data  
if that's easier, but the whole thing got me wondering about the  
quality tags that show up in other access methods. So having the  
quality information packaged with the seismograms would be a good  
long-term goal.
