Favor Needed - Can someone please forward this e-mail? Thanks!

Could someone whose access to Melvyl is still working please forward this message to domaintech at ucop.edu ?  Our servers refuse to send email to them, since their entries in Hong Kong domain name servers disappeared about 10 days ago.

Thanks for your help!

Dear domaintech at ucop.edu,

Your address is listed in the whois.arin.net database as the contact for the 128.48.0.0 - 128.48.255.255 Class B address space.  About 10 days ago, I noticed that some domain name entries for this range were no longer present in our domain name servers. I have since found that the problem is much more widespread.  Specifically, I have been trying to reach the following locations:

http://www.melvyl.ucop.edu/   University of California Library Catalog
http://www.cdlib.org/         California Digital Library
http://www.dbs.cdlib.org/     California Digital Library Databases
telnet://melvyl.ucop.org      University of Calif. Library Catalog via Telnet

To date, I have found that the following institutions appear to have this same problem:

Hong Kong University of Science & Technology
University of Hong Kong
Hong Kong Institute of Education
Hong Kong Baptist University
Carnegie-Mellon University
Princeton University
University of California at Berkeley
PCCW-HKT (Pacific Century Cyberworks / Hong Kong Telecom - ISP)

I would be most grateful if you could let me know when this problem is corrected, so that I can inform the Professors who are currently complaining to me.  Thanks.

Dear Ed,

I think there're major problem on Univ. Calif. side based on the following:

The three sites you mentioned fall into a class B ip address range
administered by 'University of California, Office of the President'
(128.48.0.0)

-traceroute from the following sites to www.cdlib.org , www.ucop.edu,
failed:
	-PCCW-HKT
	-Carnegie Mellon Univ.
	-Princeton
	-UC Berkeley

All traces failed at the same node wangty.ucop.edu (128.48.204.2).

I don't think we can help further. I think they could not receive email from
us as our email server could not reach their email server which is on the
same 128.48 network. Perhaps fax them or call them would be a better way to
reach them, then we could ask them to contact their sysadmin to check their
network.

Best regards
Raymond

>           melvyl.ucop.org (telnet)
> Also reported failing is: http://www.dbs.cdlib.org/

> 	HKUST : unable to access

> 	HKBU  : unable to access
> 	HKPU  : access works fine
> 	CUHK  : access works fine
>
> The problem has existed for about 10 days that I am aware of.

> Actions taken here:
> 1 - Notified our computer center, who are investigating.

> 5 - Wrote an e-mail to the WEB4LIB mailing list asking if anyone else
