"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues.

Author	Topic: Backfilling over night (2 messages, Page 1 of 1)

I'd like to start a year's worth of backfilling which might cross a boundary overnight from one day to the next and I am concerned that at some point, your servers might not be accessible or errors might be returned. Any thoughts or suggestions? p.s. By the way, thanks for the extra months backfill data out to a year now! I'd be even more pleased to be able to get two years. More is better in this case!

If you are looking at daily data, then there should not be anytimes that you need to worry about avoiding. If you are looking at tick or minute data, I would avoid times between about midnight and 3am EST because there is some issues with the servers converting the previous day's ticks to minutes during that time. It is a temporary issue that the server team is working on a fix for. The issue that you will encounter during this time is simply missing data. If you are requesting a single day, you will most likely get a "ERROR NONE" returned, whereas if you are requesting a year (as you mentioned), you would simply get everythign except the most recent day.
