[comp.protocols.tcp-ip] Network facilities out at PSC, Saturday July 9th

Eugene.Hastings@MORGUL.PSC.EDU (07/06/88)

[Apologies to those who see this multiple times, but I figured it's better to
see it 3 times than none. Gene]

On Saturday, July 9th, the chilled water to part of the PSC facilities will be
shut off, interrupting all long distance communications save direct dialup and
GTE TELENET. The outage is scheduled to last from 8AM to 4PM, but we hope to
have some services restored as early as 2:00PM.

Affected systems are: 
	PSN#21, 
	PSC NSS (we may or may not be able to keep the IDNX powered), 
	PSC-GW (10.4.0.14/128.182.1.1), 
	PSC-GW2 (10.1.0.21/128.182.1.7/129.250.15.7), 
	PSCMU-FW (128.182.1.8/128.2.1.1),
	PSC Fuzzball (128.182.1.2), 
	BELADY (DECNET), 
	MI-Router, 
	Pitt-Router.

This means all communications in or out of Mellon Institute, INCLUDING: 
	Transit traffic between ARPANET-NSFNET-PSCNET-SURANET-PRPNET
	Any DECNET, LAT or TCP/IP between terminals or workstations at 
	 Mellon Institute and systems at Westinghouse; 
	ALL exterior TCP/IP traffic to Westinghouse, except from Alcoa; 
	ALL exterior DECNET traffic to Westinghouse, except from Pitt; 
	ALL transit PSCNET traffic (OSU, Case or UMich to ARPA or NSFNET); 
	Transit CCNET (DECNET) traffic to or from the University of
	 Pittsburgh;
	PRPNET traffic to PSC or the University of Pittsburgh;
	INTERNET mail to or from PSC;
	Domain service which relies on CHARON.PSC.EDU (128.182.65.6)

Downtime will start at 8AM, and while we hope to have some service back by 1:00
or 2:00, events will impose their own schedule.

Since this downtime has been imposed on us, we are going to take full advantage
of it, by performing our change to a class C network number on our routing
net. 128.182.1.x will be largely replaced by 192.5.146.x. The new assignments
are:
	PSC-GW.PSC.EDU  10.4.0.14, 192.5.146.1, 129.250.15.7
	PSC-GW2.PSC.EDU 10.1.0.21, 192.5.146.2
	PSCMU-FW.PSC.EDU 192.5.146.3, 128.2.1.1
	PSC.NSF.NET      192.5.146.42

	MI-RTR.PSC.EDU 192.5.146.6, 128.182.66.1, 128.182.15.1, 128.182.16.1,
			128.167.31.2
	PITT-RTR       192.5.146.7, 130.49.5.76

	NSS		192.5.146.254

We will be changing the name servers like mad to maximize confusion :-)
