Dear all,

This is only relevant for those of you mirroring our database with TTM
traceroute data for IPv4.  All others can skip this mail.

As you know, a daily dump of the IPv4 traceroute DB is available at

Over the years, this file grown to more than 1 Gb.  This caused problems
with copying as well as with our internal operations.  As of tomorrow, May
12, the file will therefor be split into (currently 5)  files of at most
250 Mb. These will be called:

(with a 6th file to be added as soon as reaches 250 Mb).

To import the file into a mysql DB, you probably did something like:

  $ gzip -dc sqldump.gz | mysql import

This has to be replaced by

  $ cat sqldump.0.* | gzip -d | mysql import

Note that you have to copy all 5 files every time you copy the data base,
even though the size of the files appears to be the same.

Please mail tt-ops@localhost with any questions that you may have,
