Unable to connect to download updates, get wordpress rss feeds

HI there

I’m running into a problem where I am unable to automatically download updates to my wordpress installations or get rss feeds from the wordpress news and development blogs on my dashboards for these sites. In all cases the sites live on my reseller account which is web26.hspheredns.com. My ISP informs me that for some reason this particular server is being blocked at the wordpress end. Otherwise the sites run fine, and several sites I have on another account with the same ISP (Cartika) are running without difficulty.

Everything was running fine last week, but so far this week no luck. Wondering if there is something going on at the wordpress end. Did web26 offend someone?

At this point my alternative would be to move all my wordpress installs to the other account, which is work I’d prefer avoiding if possible.

Thanks
Chris
