Over the past few days, queries to multi.uribl.com have gotten ridiculously slow in the middle of the day. The average response time was over 45 seconds. If I did test queries via nslookup to 126.96.36.199.multi.uribl.com, I'd get some responses right away while others would time out entirely.
I run my own DNS servers and am not using public ones. I tested it both from my local and off-site DNS servers with the same results. I have a low volume mail server and am definitely not hitting 200,000 queries a day. Later in the afternoon/evening, I can re-enable it with no problems.
Anyone else experience the same thing?
