Blocked address range?

I use Millenicom over a Sprint tower, I think this is the appropriate forum.

Yesterday I lost the ability to connect to a site with an ip of 72.20.28.xxx.
A ping shows "Reply from Destination net unreachable."

I get this with any 72.20 address as well as 72.30.
Is this a temporary problem or is there some type of block in place?

If its a block, could 72.20.28.xxx be excluded?

I'm showing the same here, but i'm able to ping the site from all my servers just fine.

Not the best RDNS name, plus a china domain?

If this is your server/host, have you talked to them?

I thought I was alone with this issue. I've had the same problem for a few days now. Whole ranges are unreachable with my Sprint service. Right now, the affected hosts seem to be Gigeservers and Staminus. I can reach these sites via proxy so they're not down.

Using Sprint's Looking Glass service (»www.sprint.net/lg/) I can't ping or traceroute nearly anything hosted on Gigeservers and Staminus regardless of the Sprintlink server origin chosen. I don't see any maintenance windows in their list that'd indicate an issue that would be related to this problem.

That IP reverses to sl-crs3-fw-0-1-2-0.sprintlink.net. Doing my own traceroutes to affected sites, it dies at sl-crs1-kc-0-0-15-0.sprintlink.net or something similar depending on my own ip.

I wonder if Sprint's having peering issues or something. Like the Cogent issue from a year or two ago...


I have the same problem. I use an air card from Sprint and I can not reach any sites hosted by "STAMINUS-COMMUNICATIONS". I have called Sprint multiple times and they tell me it's not there fault!! If anyone has had luck figuring this out please e-mail me at aeroshade@hotmail.com THANKS!!

I'm on Sprint via Millenicom, a third party reseller.
The block appears to be gone now.
