<br />> For Malaysia, for most of its popular ISPs, the
peering is fastest through Singapore, Australia and USA-West Coast.
Frequently, speeds from these mirrors are the fastest. Yet, Malaysian
client-updates are going to a local mirror first (which is very congested),
Indonesia next (which is mind-boggling) then Singapore (which should be
second-tier) and Australia beign at the bottom.
<br />>
<br />> Local mirrors
here frequently received update requests from clients originating from countries
whose ISP peering are somewhat less nominal - Philippines, Vietnam, Cambodia,
Thailand, Indonesia and sometimes Bangladesh. Examining the <a href="http://mirrorlist.centos.org/">mirrorlist.centos.org</a> shows local
mirrors here are being listed in those countries' list at somewhat higher
priority compared to those known to be better peered.
<br />>
<br />> I'd
say we need to examine the local peering and advise the mirror-administrators,
them whom manage <a href="http://mirrorlist.centos.org/">mirrorlist.centos.org</a> to change the
order of preference for neighbouring countries mirrors-list.

<br /></span></font><font size="2">I think we're talking about two issues. For my issue,
I'm getting local mirrors (these EDU mirrors are all in the US with
decent latency to our sites). The problem is that these mirrors are unusable from
any location. Perhaps their little T1 is tapped out or something... I
think Tier1 mirror should be 1Gbps uplink or higher...nothing less...
most EDU don't have the available bandwidth to be Tier1 any longer as is becoming
very clear.

<br />
Does anyone on these school campus ever monitor those .EDU mirrors or their own network performance? Can't we just drop them for the community sake if nobody from their NOC speaks up?
