There is a very high volume of traffic coming from your site (IP address as of Wed Jan 26 14:13:25 2022 (California time). So that other users get a fair share of our bandwidth, we are putting in a delay of 15.1 seconds before we service your request. This delay will slowly decrease over a half hour as activity returns to normal. This high volume of traffic is likely due to program-driven rather than interactive access, or the submission of queries on a large number of sequences. If you are making large batch queries, please write to our public mailing list and inquire about more efficient ways to access our data. If you are sharing an IP address with someone who is submitting large batch queries, we apologize for the inconvenience. To use the genome browser functionality from a Unix command line, please read our FAQ on this topic. For further help on how to access our data from a command line, or if you think this delay is being imposed unfairly, please contact
