Yup, enough of the problem has been fixed to allow mail to flow again.

It seemed suspiciously like a path MTU discovery problem of some sort.
Pings and such worked, but anything that used larger packets failed.

Yeah. Initially I thought I was having a rerun of an MTU problem I used
to have on my own connection, but then I noticed every site I tried
except Grex was working fine.

The lag problem and the mail-delivery problem appear to have been
fixed completely.

The system is deadly slow again, both via putty and Backtalk. I assume
someone is aware there is a problem, but there's very little information,
it5 seems, about what is being done about it, or if anything is being
done. Any idea abuot what is causing the problem?

BAcktalk is barely responding at all. Half the time the pages don't load and
when they do it takes five minutes or more. I couldn't even get to the agora
screen, I had to telnet in finally just to post this

How long will it be before we move to colo? Is it really not worth even
trying to get the upstream problem resolved in the mean time?
Right now I'm even getting intermittent lag on the *dialin*. This morning
dialin was giving me a 1-2 second delay for each character.

Re. #463 & #466, postings by cross and gull, referring to "a problem with
an upstream ISP":
Does "a problem with an upstream ISP" mean: unusual use or misuse of the
dsl service by some other customer of the service in such a way as to
limit Grex' normal use of the service?

What does an upstream ISP have to do with slow dialin, which I just had for
the past 10 minutes (wait 20 sec to see the cursor move)?
If the DSL line is the problem can we cancel wtihout having to pay for the
rest of the contract?

#469...so you are saying its just a *coincidence* that these major lag issues
occurred with in days after grex moving to the new server? The timing has
to make you wonder. maybe grex would be better off back on the old server
for the time being. maybe nextgrex can't handle its job

Conditions have deteriorated the point that mail delivery seems to
have halted some time Thursday morning. Lag is bad now and I jave
had to drop one connection because it was stuck.

Dialed in. Load average 028. It just took me three tries to type that number
and I have to wait 10 sec or so to see what I typed appear onscreen.
0.28. Sometimes things go full speed, sometimes a great deal of lag.
No mail came in recently (for a few hours). How would ISP problems affect
dialins?

(richard, we've been dealing with network problems since last summer, long
before the move to the new machine.)

re #474:
> we've been dealing with network problems since last summer
the recent problems seem qualitatively different than the ongoing outages
that were occurring previously.
re #470:
> maybe grex would be better off back on the old server for the time being.
That would take a major amount of work to move back to the old server
and then another major amount of work when the new server was judged
to be ready for prime time. Worse, one might complete all that work
only to find that the source of the problem lay elsewhere, as seems to
be the current prevailing opinion among staff.

#474...gelinas, what mcnally said...the problems have clearly gotten worse,
much worse, since the switch to the new server. I understand the work that
would be involved in going back to the old server, but how else can the new
server's role in the current problems be conclusively proven?

Regarding the particular variety of intermittent screen freezing (if there
are different kinds) that we have been observing recently, when I'm logged
onto Grex and my screen happens to be frozen, are all the other screens of
other logged on Grex users also frozen <<at that moment>>, or at any given
time are some Grex screens frozen and some not frozen?
